Electron number always equals the Proton number!
N-3 ion has 7 protons and 10 electrons
A nitrogen atom has 7 protons and 7 electrons as it is electrically neutral. (An atom always has same number of protons and electrons)
There are 8 protons and 10 electrons in an oxide ion.
The atomic number of nitrogen is 7. That means that nitrogen has 7 protons per atom, each one having a +1 charge. Assuming that the atom of nitrogen is electrically neutral, there must also be 7 electrons, each of them having a -1 charge, in order for the total charge of the atom to be 0.
The protons have a positive charge and the electrons have a negative charge, so it would be 7 + -5, so the charge is +2.
The Nitrogen 3- ion. Its atomic, or 'proton' number, is 7 and remember: in a neutral atom the number of protons is equal to the number of electrons. Therefore adding 3 electrons to Nitrogen's outer shell (which allows the atom to fulfil the octet rule of having 8 valence electrons) creates an ion where there are 10 electrons and only 7 protons. The ion has a 3- charge as the balance between positive protons and negative electrons has been disrupted.
Nitrogen always has 7 protons, otherwise it is not Nitrogen. Nitrogen 20 means that there are 20 protons. Unless it has an ionic bond, then there are also 7 electrons. If it is an ion, then there are 10 electrons.

47 protons and 46 electrons.
The ion S(2-) has 16 protons and 18 electrons.
35 protons, 36 electrons
Be2+ ion has 4 protons and 2 electrons
It would be an ion.
By seeing how many protons to electrons there are. More protons, the Ion is positive. More electrons, the Ion is negative.
