1. As a result of Rutherford's scattering experiment, it was concluded that   most of the atom is empty.   the center of the atom has a negative charge.   the center of the atom is empty.   atomic mass is spread over the whole atom.   Hint Half-n-half Clue   2. The charge by mass ratio for electrons of various elements   increases with increase in atomic mass.   increases with increase in atomic number.   decreases with increase in atomic mass.   is the same.   Half-n-half Clue   3.
