An N atom is smaller than a Be atom. Why is an N3- ion much bigger than a Be2+ ion?
Select one:
a. a Be2+ ion has more protons than a Be atom; an N3- ion has fewer protons than an N atom
b. the nitrogen ion has more protons in its nucleus than does the beryllium ion
c. the nitrogen anion has a bigger amount of charge than the beryllium cation
d. cations are smaller than their neutral atoms; anions are larger than their neutral atoms

Be2+ and  N3- have the same number of electrons

but differ in protons, the more protons the higher attraction of e towards the nucleus, and a smaller radius.
