It was a hypothesis that said atoms are made of non-dividable particles.It also said atoms of one element cannot be changed into atoms of another element, this however was false. -
Thompson: The Plum Pudding Model
In this model, he was testing how negatively charged, and positively charged atoms worked together. In the end he saw how the positive and negatives would pair together. -
Rutherford: The Nuclear Model
This is a model that demonstrates how an atom has a tiny but heavy nucleus. He used radioactive particles in his experiment. -
Bohr: The Bohr (Planetary) Model
This example basically includes everything about the atom, but without all of the excess high level math. "The Bohr Model is a planetary model in which the negatively-charged electrons orbit a small, positively-charged nucleus similar to the planets orbiting the Sun (except that the orbits are not planar)." - https://www.thoughtco.com/bohr-model-of-the-atom-603815 -
Schrodinger: Quantum Mechanical Model
Created an equation to prove the statement of " We cant see an atom" wrong. It works by taking the electrons wave, and particle properties. -
