How many protons are in a nitrogen atom with a 3- charge?

A) 14

B) 15

C) 3

D) 7

Answer :

The atomic number of nitrogen (N) is 7, which indicates the number of protons present in a neutral nitrogen atom. Therefore, option D is correct.

Protons are subatomic particles that are found within the nucleus of an atom. They carry a positive electrical charge and are one of the fundamental building blocks of matter.

When a nitrogen atom has a 3- charge, it means that it has gained three extra electrons. The number of protons in an atom remains the same regardless of its charge.

Therefore, the number of protons in a nitrogen atom with a 3- charge is still 7. Therefore, option D is correct.
