Question

List the physical and chemical properties of nitrogen.

Answer 1

Nitrogen:

• Nitrogen(N) is a non-metal with atomic number 7.
• Nitrogen is the most abundant gas in the air with 78% by volume proportion.
• Some physical and chemical properties of Nitrogen are mentioned below.

Physical properties of Nitrogen:

• Nitrogen is a colorless, odorless, and tasteless gas.
• It is slightly lighter than air.
• It is slightly soluble in water.
• It is a non-poisonous gas but animals die due to suffocation of nitrogen.

Chemical properties of Nitrogen:

• It is non-combustible gas neither does it support burning.
• It is chemically inert under ordinary conditions.
• Nitrogen reacts with certain metals to form metal nitrides. Example: Nitrogen reacts with Calcium to form Calcium nitride.

$\underset{\mathrm{Calcium}}{3\mathrm{Ca}\left(\mathrm{s}\right)}+\underset{\mathrm{Nitrogen}}{{\mathrm{N}}_2\left(\mathrm{g}\right)}\to \underset{\mathrm{Calcium}\mathrm{nitride}}{{\mathrm{Ca}}_3{\mathrm{N}}_2\left(\mathrm{s}\right)}$

• Nitrogen combines with oxygen to form oxides of nitrogen.

$\underset{\mathrm{Nitrogen}}{{\mathrm{N}}_2\left(\mathrm{g}\right)}+\underset{\mathrm{Oxygen}}{{\mathrm{O}}_2\left(\mathrm{g}\right)}\to \underset{\mathrm{Nitric}\mathrm{oxide}}{2\mathrm{NO}\left(\mathrm{g}\right)}$
