Relative to protons, electrons have:
A. significantly greater mass.
B. significantly less mass. approximately the same mass.
C. a significantly stronger positive charge.
D. None of the above is correct.
E. Electrons have no mass.

The mass (in g) of an electron is 9.11 ×[tex]10^{-28}[/tex]g, which is significantly lower than the mass of protons and neutrons which are approximately the same. They are extremely small (equal to 0 amu), contributing nothing to the overall mass of the atom.

The nucleus has a mass of 1 amu and is positively charged.
