(0.4)HISTORY OF ATOM- Antimony explains

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 orbited the nucleus in a wide orbit. That is why it is known as

the planetary model.

Hmm. My guy called it planetory model cause it looked like a planet according to him o.🤗🤗🤗

People accepted his idea until another cute guy arose to modify his result. Let's live that for (0.5) next post.

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

CELLS-Antimony explains😊

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

WHY THE SKY IS BLUE-Antimony explains

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
