Question

Why oxygen can't extend its valency from 2

Answer 1

Explanation:

Atoms need energy to either gain or lose electrons so it is easier for oxygen to gain 2 electrons and be in octet configuration nearest to inert gas Neon(2,8) than to lose 6 electrons to be in duplet configuration nearest to inert gas Helium(2). That's why oxygen gains two electrons and has valency of two.
