Scientists had now established that the atom was not indivisible as Dalton had believed, and due to the work of Thomson, Millikan, and others, the charge and mass of the negative, subatomic particles—the electrons—were known. However, the positively ... WebAnswers. All matter is composed of atoms; atoms of the same element are the same, and atoms of different elements are different; atoms combine in whole-number ratios to form compounds. A proton is larger than an electron. proton: 1+; electron: 1−; neutron: 0. The atomic number is the number of protons in a nucleus.
