Question

Element A belongs to Group VII in p-block and element B belongs to Group I in s-block of the periodic table. Out of the following assumptions, the correct one is : * 1 point A is a metal and B is a non-metal A and B are metals A and B are non-metals A is a non-metal and B is a metal

Answer 1

4) A is a non-metal and B is a metal.

Explanation:

Element A is a member of Group VII in p- block

• This implies that element A has seven valence electrons which will try to attain a stable octet configuration, hence it will act as a non-metal.

Element B is a member of Group I in s- block

• This implies that element A has one valence electron which can be lost easily, hence it will act like a metal.

The correct answer is  A is a non-metal and B is a metal.
