The nitride ion, #"N"^(3-)# has 7 protons and 10 electrons.

Explanation:

The formula of the nitride ion, #"N"^(3-),# indicates that a nitrogen atom has gained 3 additional electrons.

Nitrogen has atomic number 7, which means its atoms have 7 protons in their nuclei. In a neutral nitrogen atom, there would also be 7 electrons. But since the nitride ion has a #3^-# charge, it has gained an additional 3 electrons.

The nitride ion has 7 protons and 10 electrons.

The nitride ion consists of 7 protons and 10 electrons.

Explanation:

Nitrogen has an atomic number of 7. The atomic number tells you how many protons an atom or ion has.

The nitride ion has a charge of -3. The charge is the result of an addition of three electrons which complete the valence shell of the particle.

Charge determination

+7 = charge from seven protons each with a +1 charge
-10 = charge from 10 electrons each with a -1 charge
-3 = net charge of a nitride ion
