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 has 7 protons and thus 7 electrons to be neutral. It's total configuration is 1s2 2s2 2p3. Therefore, its valence configuration is 2s2 2p3. Nitrogen has 7 protons and thus 7 electrons to be neutral. It's total configuration is 1s2 2s2 2p3. Therefore, its valence configuration is 2s2 2p3.
