Question

i. Write the general outer electronic configuration of the elements of group 13, group 14 and group 15. 

ii. By how many electrons do their outer electronic configurations differ from their nearest inert gas?

Answer 1

i.

Group	General outer electronic configuration
13	ns2 np1
14	ns2 np2
15	ns2 np3

ii. The outer electronic configurations of the elements group 13, group 14 and group 15 differ from their nearest inert gas by 5, 4 and 3 electrons, respectively.
