Nitrogen is classified as an element in the 'Non-Metals' section which can be located in groups 14,15 and 16 of the Periodic Table. Non-metallic elements exist, at room temperature, in two of the three states of matter: gases (Oxygen, Hydrogen & Nitrogen) and solids (Carbon, Phosphorus, Sulfur and Selenium).
Nitrogen is element 7, so it has 7 protons. Nitrogen-14 would have atomic weight of 14, so it has 14-7 = 7 neutrons. How many electrons is a tricky question.Uncharged atomic Nitrogen would have 7 electrons, one for each proton, but it does not occur naturally in in atomic form. Nitrogen in its ground state is diatomic molecule with a covalent triple-bond.eport Abuse. Nitrogen is element 7, so it has 7 protons.
