Atomic theory is a scientific description of the nature of atoms and matter that combines elements of physics, chemistry, and mathematics according to modern theory, matter is made of tiny particles called atoms, which are in turn made up of subatomic particlesatoms of a given element are identical in many respects and different from atoms of other elements. 400bc ish indivisible, solid sphere model developed by democritus he said all matter is composed of indivisible tiny things made up into small not being able to be. Atomic theory timeline project cat gordon democritus -- circa 400 bc democritus, a greek philosopher, was the first person to propose the existence of atoms democritus is known as the father of modern science however, he did not work alone he studied under the greek philosopher leucippus in fact, leucippus had a great impact on his.

Thompson made a theory that these electrons were the very building block of atoms he called these building blocks corpuscles he discovered these negatively charged particles using the cathode ray niels bohr bohr made a model of a hydrogen atom that included the electrons of the atom he created.

Atomic model timeline

The currently accepted model of the atom was created by erwin schrodinger many years later, known as the schrodinger model (or the wave mechanical model), it states that electrons do not move in orbits around the nucleus rather, they move in random waves in a “cloud” (atomic structure timeline. Jj thomson was a very important scientist when it came to the atomic model up until his time, all models of the atom looked like a big solild ball jj thomson discovered the electron, which led him to create the plum pudding atomic model. Jj thompson proposed the plum pudding model of the atom when he discovered electrons, and ernest rutherford countered with the nuclear atom when he discovered the nucleus in the gold foil.
