The Atomic Theory

The Atomic theory is just another law or principle of science, its the very foundation of all that science includes! The laws and principles of science were able to be tested because of this theory! We are going over everything about the atomic theory including its beginning, the history of the atomic theory, and why it is so important in the first place. We will also go over the many models produced by scientists over the years and why they were right or wrong and then our final result. The Atomic theory went through a number of different stages before it actually came near to being complete, and even now we still may be wrong or at least be able to do better than our current standard model.

As we know today, the

It was said to believe that the Atom itself was Fundamental and that nothing was smaller. The theory was first proposed by the Greek philosopher Democritus. He named the atom the Atomon, which meant indivisible. His famous quote is “by convention sweet, but in reality atoms and void". He proposed this in the Greek era, specifically around 400 BCE. Later on in 1704, Isaac Newton looked at Democritus 's work. He believed that atoms were indestructible. He also believed that they all differed in both shape and size. He also believed that there was an unlimited amount of atoms. His theory specifically included that all matter consists of invisible particles called atoms, atoms are indestructible, atoms are not solid but invisible, atoms are homogenous, and that atoms differ in size, shape, mass, position, and arrangement. Another Greek philosopher whose very existence can be argued, Leucippus, was also thought to have contributed the idea of philosophical atomism to the atomic theory, but again, his very existence can be argued.

Then again in 1803, John Dalton, and english chemist, proposed a improved atomic theory. His theory consisted of four principles. One, all matter is made of atoms. Atoms are indivisible and indestructible. Two, all atoms of a given element are identical in mass and properties. Three, Compounds are formed by a combination of two or more different kinds of atoms. And four, A chemical

Also, a german physicist named Werner Heisenberg established the uncertainty principle in 1927 which pretty much says that the position and the momentum of a subatomic particle can be stated at the same time. “The quantum theory is the theoretical basis of modern physics that explains the nature and behavior of matter and energy on the atomic and subatomic level.” Says “The Nanotechnology Glossary.” Albert Einstein also contributed to the quantum theory by using Planck 's original theories to establish the idea of the photoelectric effect. This was the act of electrons emit from metals after being radiated. By observing this, he could tell the energy of the electrons by changing the frequency of the radiation. The higher the frequency, or energy level, the more electrons were
