(0.1)HISTORY OF ATOM- Antimony explains

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(0.2) next post. 🤗🤗

GENE- Antimony explains

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 ...

CHROMOSOMES- Antimony explains

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 g...

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 proton...
