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).
Nit rogen is a non-metal. A nitrogen atom has 5 electrons in its outer shell. Nitrogen is in group 5 of the periodic table. Two nitrogen atoms will each share three electrons to form three covalent bonds and make a nitrogen molecule (N2). This is a picture of a nitrogen molecule.By sharing the six electrons where the shells touch each nitrogen atom can count 8 electrons in its outer shell.wo nitrogen atoms will each share three electrons to form three covalent bonds and make a nitrogen molecule (N2).
