Answer 2

The blanks are filled by using brackets ( )

(a) Formula of ion of A is A2+. Element A probably belongs to ( 2nd ) group.

(b) In a period, ( increase ) in electron affinity results in reduction.

(c) On descending down a group, ( increase ) in ionisation potential as well as electron  affinity  ( decreases ) oxidising  capacity.
