There is a considerable increase in covalent radius from N to P.

However, from As to Bi only a small increase in covalent radius is observed. This is due to the presence of completely filled d and f or f orbitals in heavier members. The tendency to exhibit —3 oxidation state decreases down the group due to increase in size and metallic group. In the last member of the group, bismuth hardly forms any compound in —3 oxidation state. Because of the extra stable half filled p orbitals electronic configuration and smaller size, the ionization enthalpy of the group 15 elements is much greater than that of group 14 elements in the corresponding periods.

However, amongst the heavier elements, the different is not that much pronounced. Uses of Neon: i Neon is mainly used in fluorescent lamps of tubes for advertising purposes. These are known as neon signs and can be seen at long distances even when there is a fog. Neon actually produces an orange red glow in the tube and on mixing with the vapours of other gases, glows or signs of different colours can be obtained.

Uses of Argon: i It is used in metal filament electric lamps since it increases the life of the tungsten filament by retarding its vapourisation. Chapter Chosen The p-Block Elements.
