Give the characteristics of p- block elements.

Explanation

Characteristics of p- block elements :
(i) General electronic configuration is
`ns^(2)np^(1-6)` (Group 13 to 18).
(ii) They are generally non - metals but some metals and metalliods are present.
Non - metallic character increases from left to right along period.
Metallic character increases on moving down a group
(iii) They have electron affinity and ionization enthalpy .
both the properties increases along the period.
Both the properties decreases on moving down the group
(iv) Oxidising character.
Increases on moving from left to right along a period.
Reducing character increases from top to bottom in a group.
(v) s- block and p- block elements are collectively called representative elements.
