Question

answer this guys plzzzzzz​

Answer 1

Answer:

table is wrong instead if period group must be there....

I) E can form only covalent compounds

ii) B is the metal who's valancy is three as general configuration of 13th group is ns²np¹ (they can loose three electrons)

iii) C is the non metal who's valancy is three as general configuration of 15th group is ns²np³ (they can accept three electrons)

iv) Among B and C, C is greater in size than B as size decreases in a period and increases in group.

Answer 2

Explanation:

1) element E placed in group 14 will form covalent compound as it's valency is 4.

2) element B is a metal having valency 2.

3) element C is a non metal having valency 3.

4). is rong question because it is not in same group or same period
