ANTIMONY

  Antimony-Explains Why is the sky blue? It’s a common misconception that the sky is blue because it reflects the blue of the seas and oceans. A lot of myths have also been told about our blue sky😉. That is why Antimony is here for you. To debunk those non relevant ideas.😊 As for the seas reflection it is very wrong. In fact, it’s the Earth’s atmosphere, and a process known as 'scattering', that causes our skies to be blue.   So what is this scattering. As white light passes through our atmosphere, tiny air molecules cause it to ‘scatter’. The scattering caused by these tiny air molecules (known as Rayleigh scattering) increases as the wavelength of light decreases. Violet and blue light have the shortest wavelengths and red light has the longest. Therefore, blue light is scattered more than red light and the sky appears blue during the day. When the Sun is low in the sky during sunrise and sunset, the light has to travel further through the Earth’s atmosphere. We don’t see t

  What is cell? Maybe you have heard of that word before..🤔   Cell is the basic building blocks of all living things.😋  intresting right?.  The human body is composed of trillions of cells. They provide structure for the body, take in nutrients from food, convert those nutrients into energy, and carry out specialized functions. Cells also contain the body’s hereditary material and can make copies of themselves.😊😐 Cells have many parts, each with a different function. Some of these parts, called organelles, are specialized structures that perform certain tasks within the cell. Human cells contain the following major parts which am going to list in alphabetical order: Cytoplasm Within cells, the cytoplasm is made up of a jelly-like fluid (called the cytosol) and other structures that surround the nucleus. Cytoskeleton The cytoskeleton is a network of long fibers that make up the cell’s structural framework. The cytoskeleton has several critical functions, including determining cell s

  What is a chromosome?  In the nucleus of each cell, the DNA molecule is packaged into thread-like structures called chromosomes.😮 Each chromosome is made up of DNA tightly coiled many times around proteins called histones that support its structure. Chromosomes are not visible in the cell’s nucleus—not even under a microscope—when the cell is not dividing. However, the DNA that makes up chromosomes becomes more tightly packed during cell division and is then visible under a microscope. Most of what researchers know about chromosomes was learned by observing chromosomes during cell division. Each chromosome has a constriction point called the centromere, which divides the chromosome into two sections, or “arms.” The short arm of the chromosome is labeled the “p arm.” The long arm of the chromosome is labeled the “q arm.” The location of the centromere on each chromosome gives the chromosome its characteristic shape, and can be used to help describe the location of specific genes. DNA

  What is gene? Hmm. Sounds weird.  A gene is the basic physical and functional unit of heredity. Genes are made up of DNA. Some genes act as instructions to make molecules called proteins. However, many genes do not code for proteins. In humans, genes vary in size from a few hundred DNA bases to more than 2 million bases. An international research effort called the Human Genome Project, which worked to determine the sequence of the human genome and identify the genes that it contains, estimated that humans have between 20,000 and 25,000 genes. Every person has two copies of each gene😮, one inherited from each parent. Most genes are the same in all people, but a small number of genes (less than 1 percent of the total) are slightly different between people. Alleles are forms of the same gene with small differences in their sequence of DNA bases. These small differences contribute to each person’s unique physical features.🤔 Scientists keep track of genes by giving them unique names. Be

 What is DNA? 🤔 Are you thinking what am thinking?😂 DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA). Mitochondria are structures within cells that convert the energy from food into a form that cells can use. The information in DNA is stored as a code made up of four chemical bases: adenine (A), guanine (G), cytosine (C), and thymine (T). Human DNA consists of about 3 billion bases, and more than 99 percent of those bases are the same in all people. The order, or sequence, of these bases determines the information available for building and maintaining an organism, similar to the way in which letters of the alphabet appear in a certain order to form words and sentences. Adenine always fix with Thy

Ohh. Now in 1920 this Scientist;Erwin Schrödinger vex and scatter everywhere with his new hypothesis.🤓 Erwin Schrödinger was a revolutionary physicist who used Heisenberg’s  uncertainty principle to come up with the atomic model that we still use today. SCHRÖDINGER’S ATOMIC MODEL (AKA THE CLOUD MODEL)  After doing a lot of work he concluded these salient points am going to alight now. They include: 1. An electron does not travel in an exact orbit😗 2. We can predict where it will probably be😙 3. We cannot say for certain where it is, but only where it ought to be.😚 4. The type of probability orbit is dependent on the energy level described by Bohr☺ Let's now summarize what we know of atoms. The smallest part of an element is called an atom Each atom (of an element) is different in structure from  other atoms (of other elements) An atom can be divided in smaller subatomic particles: Protons, Electrons and Neutrons The nucleus is the centre of an atom. It contains protons and neut

 Not until around 1910 when Ernest Rutherford doubted the already existing atomic model. Rutherford was not convinced about the model of the atom  proposed by Thomson. He thus set up his now famous Gold Foil  Experiment.  1. He fired alpha particles (positively charged) at a gold  foil.😮 2. He measured the deflection as the particles came out  the other side.🤥 3. Most of the particles did not deflect at all. Every now and then a particle would deflect all the way back.🤔 4. He said that there must be a positive centre of the foil. He called this centre the nucleus🙄. Let's look at what he got from his experiment. RUTHERFORD’S ATOMIC MODEL (AKA THE PLANETARY MODEL) 1. The nucleus of the atom is a dense mass of positively  charged particles. 2. The electrons orbit the nucleus 3. A problem raised was: Why are the negatively  charged particles not attracted by the positively charged  nucleus🤔 4. Rutherford stated that the atom was like a mini solar system and that the  electrons orb

Learn with Antimony. Hmm. After many years I met Niels Bohr. Niels Bohr told me he agreed with the planetary model of  the atom, but also knew that it had a few  flaws.🤔 Using his knowledge of energy and  quantum physics he was able to perfect  Rutherford’s model. He was able to answer  why the electrons did not collapse into the  nucleus.☺ BOHR’S ATOMIC MODEL (AKA THE RUTHERFORD-BOHR MODEL) I think it was just modification of Rutherford experiments😋 This was the experiment Rutherford Carried out, where he fired alpha particles at gold foil This includes that: 1. Electrons orbit the nucleus in orbits that have a set  size and energy.  2. The lower the energy of the electron, the lower the  orbit. 3. This means that as electrons fill up the orbitals, they  will fill the lower energy level first.🤔 4. If that energy level is fill (or at capacity), a new  energy level will begin. 5. Radiation is when an electron moves from one level to another. Problems with this theory:  Electrons do n

I could remeber during the 1890’s when I met this friend of mine who contributed a lot to the discovery and explanation of the atom, I call him J.J Thomson😋 J.J Thomson was a physicist who is credited for discovering the  electron.😙 He used his research on cathode ray tube technology in this  discovery.  CATHODE RAY TUBE (stop wondering. Antimony got you) How does this Tube Work?🤔 1. Nearly Empty tube (Air has been sucked out)😉 2. An electric charge is passed through the tube. Travels from cathode to  anode😮 3. The charge is invisible, so to see where it traveled a fluorescent screen is  placed at back of tube. Where the beam hits, a  dot will appear on the screen. You could also use a  fluorescent gas and the whole tube will light up.😫 4. This beam will always travel straight if not  interfered with.😏 5. The deflection coils each have a specific charge.  One is positive and the other is negative.🤐 6. Thomson showed that  the charge would deflect away from the negative  coil. H

John Dalton😋 Around 1800 BC.   my friend then was John🙂 John Dalton was the first to adapt Democritus’ theory into the first modern atomic  model. According to John:  1. All matter consists of tiny particles called  atoms 2. Atoms are indestructible and unchangeable 3. Elements are characterized by the weight of their atoms 4. When elements react, it is their atoms that have combined to form new  compounds I hope you dey grab😋                  By: Oshinowo Testimony                         Antimony😎

Learn with Antimony. Let me introduce you to this great man called Democritus in the early 400 BC Scientist: Democritus (Greek Philosopher) He was a Greek philosopher who was  the first person to use the term atom (atomos:  meaning indivisible). You must have heared that before right?🤔 He thought that if you take a piece of matter  and divide it and continue to divide it you will  eventually come to a point where you could not  divide it any more. This fundamental or basic unit was what Democritus called an  atom. He called this the theory of the universe: All matter consists of atoms, which are bits of matter too small to be  seen. After all His researches he concluded that; There is an empty space between atoms Atoms are completely solid Atoms have no internal structure Each atom (of a different substance) is different in size, weight and  shape. Hmm. This guy made a salient point. But as time goes on let's see what will happen to his most respected theory about atoms 🙂 in the(

What are phobias? A phobia is an excessive and irrational fear reaction. If you have a phobia, you may experience a deep sense of dread or panic when you encounter the source of your fear. The fear can be of a certain place, situation, or object. Unlike general anxiety disorders, a phobia is usually connected to something specific. Do you get it😊 The impact of a phobia can range from annoying to severely disabling. People with phobias often realize their fear is irrational, but they’re unable to do anything about it. Such fears can interfere with work, school, and personal relationships. Remember those your pretty anomalous friends😉 An estimated  19 million Americans  have a phobia that causes difficulty in some area of their lives. Seek the help of your doctor if you have a fear that prevents you from leading your fullest life. Causes Genetic and environmental factors can cause phobias. Children who have a close relative with an  anxiety disorder  are at risk of developing a phobia.

  Solar energy   is any type of energy generated by the   sun . As you all know🙂 Solar energy is created by  nuclear fusion  that takes place in the sun. Fusion occurs when protons of hydrogen atoms violently collide in the sun’s core and fuse to create a helium atom. You can also check: https://education.nationalgeographic.org/resource/solar-energy/ This process, known as a PP (proton-proton) chain reaction, emits an enormous amount of energy. In its core, the sun fuses about 620 million metric tons of hydrogen every second. The PP chain reaction occurs in other  stars  that are about the size of our sun, and provides them with continuous energy and heat. The temperature for these stars is around 4 million degrees on the  Kelvin scale  (about 4 million degrees Celsius, 7 million degrees Fahrenheit). In stars that are about 1.3 times bigger than the sun, the CNO cycle drives the creation of energy. The CNO cycle also converts hydrogen to helium, but relies on carbon, nitrogen, and oxy

 T hose bright color you see most after after a heavy rainfall. And you were told a lot of fairy tales about them. I will explain here so you will gain knowledge.   A   rainbow   is a multicolored   arc   made by light striking water droplets. Are you grabbing🤗 The most familiar type rainbow is produced when  sunlight  strikes  raindrops  in front of a viewer at a precise angle (42 degrees). Rainbows can also be viewed around  fog , sea  spray , or  waterfalls .  A rainbow is an  optical illusion —it does not actually exist in a specific spot in the sky. The appearance of a rainbow depends on where you're standing and where the sun (or other source of light) is shining. The sun or other source of light is usually behind the person seeing the rainbow. In fact, the center of a primary rainbow is the  antisolar point , the imaginary point exactly opposite the sun. I hope my vocabularies are understandable😐😐😐 Rainbows are the result of the  refraction  and  reflection  of light. Bo
