The Founding Fathers of the Atom: Part 2

John Dalton may have been the first to give us an idea of what an atom is, but JJ Thomson discovered a highly important part of the atoms. Thomson found that there were tiny electrons in the atom, and in his theory, he states that they are scattered throughout the atom. This model is referred to as the chocolate chip model where the electrons are the chocolate chips, and the rest of the cookie is the remaining mass of the atom.
