Question

All metals react with nitrogen on heating.

• A. True
• B. False

Answer 1

The correct option is B False

The nitrogen atom has the electronic structure represented by $1s^{2}2s^{2}2p^3$. The electronic configuration includes three half-filled outer orbitals which give the atom the capacity to form three covalent bonds.

Thus when nitrogen molecule is heated with metals which have a lower electronegativity than nitrogen forms covalent bond giving metal nitride
