1. a. p will have valency +2

Q will have valency 4

R will have valency -1

because group 2 elements have 2 valence electrons and they are metals so they losses 2 electrons to full fill their outer most shell. but group 14 and 17 elements have 4 and 7 valence electrons respectively and they are non metals so they gains 4 or 3 electrons to full fill their outer most shell.

2. a. basic oxide,b. acidic oxide , c. acidic oxide
