1. E forms covalent compounds
2. D is the metal
3. B is the non metal with valency 3.
4. E has greater atomic radius because as we go across the period the no of electrons keeps increasing as a result the effective nuclear charge increases, Decreasing the atomic radius.
5. C belongs to halogens family and F belongs to the noble or the inert gases.
Hope this helps!.
