Kindly 9th one with proper explanation
Hi,
a) A is a non metal : In a periodic table, Group 15 lie at right hand side of the periodic table and when we move across left to right in a period metallic character decreases.
b) D is more electronegative than E : Down the group electronegativity decreases due to increase in size and decrease in nuclear effect down the group.
c) Anion formed by C is C2-. It can easily gain 2 electrons and achieve noble gas configuration.
Regards
