About Nitrogen
- Nitrogen makes up 78% of the air.
- Nitrogen has the chemical symbol N.
Molecular Structure
- The chemical formula for a Nitrogen molecule is N2.
- Nitrogen forms a covalent bond with another Nitrogen atom to produce a simple covalent molecule.
Atomic Structure
- The most common stable isotope of Nitrogen has 7 neutrons in its nucleus giving it an atomic mass of 14.
- Nitrogen is in Period 2 of the Periodic Table because it has 2 electron shells.
- Nitrogen has 5 electrons in its outer shell and needs 3 more electrons to get a full outer shell so it can form 3 bonds with other atoms.
