Question

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.

Answer 1

(B.) a significantly lower mass that protons

Step-by-step 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.
