The charge of N^-1 is -1
To find the protons, look on a period table, and find the atomic number. Atomic number = protons
Atoms have the same number of protons and eletrons because they have to balance.
Regular N is not ionic, so it has no charge I think.
Since this is N^-1, it will have one fewer electron than the number of protons.
Regular nitrogen is N2.
