Atomic number of an element is 16. Predict:-
(a) its valency
(b) whether it is metal or a non metal

Solution

It's configuration is 2,8,6 therefore it's valency is 2 as it needs two electrons to complete its octet.
It is a non metal because as we go from left to right in a periodic table the metallic character decreases while non-metallic character increases.
