- Rutherford proposed ( ) by analyzing the results of the α particle scattering experiment A: Atomic nuclear structure model B: There are neutrons in the nucleus C: Electrons are part of atoms D: The nucleus is made up of protons and neutrons
- The atomic weight of an atom, or the molecular weight of a molecule, is its mass relative to that of a(n) ________ atom. This is essentially equal to the number of protons plus neutrons that the atom or molecule contains.
