How Many Electrons, Protons, and Neutrons Are There in a Nitrogen Atom?

Seven protons, seven neutrons, and seven electrons make up one neutral atom of nitrogen. The Periodic Table of the Elements’ group 15 and period 2 both contain this element. It is 14.007 amu in atomic weight.

The periodic table’s seventh element is nitrogen. It possesses seven protons since it has an atomic number of seven. The mass number of nitrogen is 14 due to its atomic weight of 14.007 amu. The number of neutrons in the atom can be calculated by subtracting the number of protons (7) from the element’s mass number (14)

Seven neutrons are present in many nitrogen atoms (14-7 = 7). However, some nitrogen atoms contain eight electrons. These are nitrogen isotope N-15 atoms.

Protons and electrons must have an equal quantity in a neutral atom. This implies that a neutral nitrogen atom needs seven electrons to go along with its seven protons.
