Question

Relative to protons, electrons have:

Answer 1

Answer:

(B.) a significantly lower mass that protons

Explanation:

The mass (in g) of an electron is 9.11 ×$10^{-28}$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.
