1.

They can differ in number of neutrons (forming isotopes), and in the number of electrons.
For instance for isotope: C-12 Vs C-14
For the way they differ in the number of electrons: C+ Vs C Vs C-.

Carbon vs. Uranium atoms
– different number of protons
– different number of neutrons
– different number of electrons
2.

The symbol N represents the element nitrogen and stands for the naturally occurring mixture of all isotopes, hence symbols 15N and 14N are isotopes of the same element – consequently they have different mass numbers of 15 and 14 respectively.
