Look at your periodic table and figure out what atom has 7 protons in it.
Then look at the atomic mass of this element and figure out how many neutrons are in it by subtracting the number of protons from the atomic mass.
Then look up naming rules for ions.

Any atom or ion with 7 protons is nitrogen. If it has 10 electrons, it's N 3-. There's no way to tell from the information given how many neutrons it has. Nitrogen has three isotopes with 6, 7, and 8 neutrons respectively. The one with 6 neutrons is radioactive, and doesn't exist in nature, only in labs. About 99.6% of all the nitrogen on Earth has 7 neutrons, so that's what I'd guess. The other 0.4% has 8 neutrons.

protons is the atomic number, so looks that up on the periodic table....7.....
to find the neutrons, you take the rounded atomic mass and subtract the number of protons from it. If you cant figure it out, email me.
also to find the charge on the ion, use protons - electrons.... if answer is a + one, you have a + ion (cation) if the answer is -, you have a - ion ( anion)

This is the nitride ion, N 3-. Most likely, the number of neutrons is 7, as N-14 is the most common isotope of nitrogen.

Number of protons gives atomic number. check in periodic table atomic number 7 is nitrogen
