Jul 16, 2011  · Who Discovered the Atom. Today, John Dalton is considered to be the father of the modern atomic theory. Much work was done after John Dalton proposed the theory of atoms, but it was physicist J. J. Thomson who, in 1897, discovered the electron. This was the inspiration for the modern idea of electron’s rotating around the nucleus.

Rutherford proved in 1911, that there was a nucleus. He did this directly by shooting alpha particles at other atoms, like gold, and observing that sometimes they bounced back the way they came. There was no way this could be explained by the current picture of the atom which was thought to be a homogeneous mix.

Atoms Bond Together To Form Mapping atoms across chemical reactions. it transforms the substrate into a decoy form (see examples in Fig. 4) that is significantly less similar to the product. Consequently, more bonds need to. In order to reach a state of stability, atoms bond together to form molecules by sharing their valence electrons, or electrons that make up the outermost shell.
