Nitrogen was discovered by Rutherford in 1772 and is named 'Nitrogen' from the Greek language.

Some common usages for Nitrogen: present in the atmosphere.

Definitions and Notes

Density listed is at a temperature of 20°C.

Isotopes are forms of an element who have the same atomic number but different mass because they contain different number of neutrons.

Half-life is the time required for a quantity of a subject to fall to half of its current quantity.
