Question

An atom of nitrogen has seven protons in its nucleus. how many electrons does it have

Answer 1

It will have seven electrons.

Answer 2

The nitrogen atom consists of 7 protons and 7 electrons as the nitrogen is electrically neutral. Nitrogen is the seventh element in the periodic table. Its atomic number is 7. so, it also consists of seven protons.

Nitrogen atomic mass is 14, so subtracting the number of protons from the mass number we will get the number of neutrons in the nitrogen atom.

Hence, there are 7 electrons in the nitrogen atom.
