What is the oxidation number of a group 1a compoubds?

SVETLANKA909090 [29]

Answer:-

Explanation:-

Group 1 A compounds has 1 valence electron.

According to the octet rule, if outermost shell has 8 electrons then it is stable.

So Group 1 A compounds lose 1 electron to fulfill octet.

Oxidation number is the number of electrons lost or gained. It is positive if electrons are lost and negative if electrons are gained.

Hence the oxidation number of group 1 A compounds is +1.
