Atomic Theory

The atomic theory was a theory based on the idea that every item in this world could be broken down into an extremely small particle called the atom. If the idea had never been presented and recorded, then there would have been no attempts to prove it, and science would have suffered as a result.

Dealing with the events before the birth of Christ, the only significant scientific development was in sixth century B.C. It was the discovery of static electricity by rubbing a piece of amber against fur and observing that the fur stood on end. Thalleus of Maletus believe that this power was derived from the amber, not to any particle. A man by the name of Democritus thought it was something else two centuries later. He believed that all matter was permanently divisible into eensy-beensy particles called atoms that had statical electric properties (Atoms).

We now enter a period called the Dark Ages. If events ever took place, they were not recorded. Let us now jump into our time machine towards 1803...

In 1803, John Dalton theorized that if all atoms exist, they must follow the Law of Conservation of Mass and the Law of Proportions. His beliefs were published as “The Atomic Theory.” The f


During 1912, Niels Bohr theorized that electrons did not spin into the nucleus. The theory also stated that electrons orbit at certain allowed distances and atoms radiate energy when an electron jumps from a higher energy orbit. “`Here's some rules that seem impossible, but they describe the way atoms operate, so let's pretend they're correct and use them’,” said Niels Bohr himself. Alas, he changed it to make it less vague. He worked with Arnold Summerfeld to develop a new theory, which stated that orbits can appear circular or elliptical and can go through the nucleus (Atoms).

ive postulates were: All matter has definite particles called atoms, atoms are indestructable, atoms of one particular element are identical, and when atoms combine they make more complex particles (Dalton’s Atomic Theory).

In 1896, the proton was observed by E. Goldstein. Upon reading this report, a man named Joseph Thomson instantly became fascinated by this and devoted his time to solely the Atomic Theory. He eventually discovered in the same year the existence of positive and negative charges in subatomic particles (Atomic Theory).

The following year, Thomson discovered the electron using a cathode
