Atomic or molecular?
Atomic would mean Nitrogen (with 7 protons) with a -3 charge (electrons - protons = charge). The symbol would be:
N^-3 [N raised to the -3]
One possible molecular ion would be (BH2)^-2 I do not know if this is real. It would be a Boron Hydride ion.

well, if it has 7 protons, then it is nitrogen
look at the periodic table, atomic number 7, nitrogen
if a nitrogen atom has 7 electrons also, then it is neutral, and is no kind of ion, just regular nitrogen
if an atom has more electrons than protons, then it has a net negative charge
with three extra electrons it will have a net negative charge of 3
I'm not that great on correct nomenclature, but I would write the symbol as N ^3- (where the ^ means that the 3- should be a superscript)
does that match what your book says?
you may have to take the concept and see how your book writes negatively charged ions
good luck
use the periodic table, its full of information

it is a hypothetical question, if the proton are 7 the element is Nitrogen , but nitrogen doesn't ionized, it is linked covalently like in NH3, and the unshared pair in NH3 will give a dative bond to an ion to produce ammonium ion.
return back to your question if an element gains electrons it will be negative ion, and the charge will be as the number of gained electrons.

Fe-3
The chemical symbol for iron is Fe. There are 3 more electrons then protons. So the charge is -3.

N-3 (The minus three should be a superscript.)
