Phosphorus shows greater tendency for catenation than nitrogen. Why ?

Phosphorus shows greater tendency for catenation than nitrogen. Give examples.

How would you account for the following : (i) The electron gain enthalpy with negative sign is less for oxygen than that for sulphur. (ii) Phosphorus shows greater tendency for catenation than nitrogen. (iii) Fluorine never acts as the central atom in polyatomic interhalogen compounds.
