What is rubidium nitride?

Rubidium nitride is a chemical represented by the molecular formula Rb3N. Each molecule of rubidium nitride contains three atoms of rubidium and one atom of nitrogen.

Rubidium nitride burns when exposed to oxygen in the air, creating the toxic gases rubidium oxide and a combination of nitrogen and oxygen. It has a molar mass of 270.41 grams per mole. The chemical is made from rubidium ions with a charge of plus one and nitride ions with a charge of minus three, both of which can be determined from either the name or formula of the compound. More common compounds of rubidium and nitrogen include rubidium nitrate, represented by the formula RbNO3.
