The pre-modern idea of atomic theory was proposed by Greek thinkers like Democritus, Leucippus, and the Epicureans, which would have been at about 500 to 300 BC.

J.J. Thomson's scientific ideas were called the atomic theory. In 1897 he discovered the electron and came up with a new theory that atoms were made up of small particles.
Dalton came up with that theory. It was proven wrong, though.
Neils Bohr came up with the kinetic Theory of Matter, also known as: The Molecuar Theory of Matter, and The Bohr Model.
He came up with the theory.
J.T Wilson was the one who came up with the theory of plate tectonics. Harry Hess came up with the theory of sea-floor spreading. Alfred Wegener came up with the theory of continental drift and Arthur Holmes proposed a suitable mechanism for this to occur (mantle convection).
The concept of atoms, or particles that make up all of matter, is an ancient one. However, John Dalton came up with the first scientific atomic theory in the early 1800s.

I'm sorry, I don't know what that means. Maybe this: Atomic theory is a theory that matter is made up of small particles called atoms
Dalton viewed chemical change as the process of atom rearrangement. Using the atomic theory he came up with, he believed that chemical reactions rearranged the atoms into different combinations.
