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

-

+1

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.

a 20-cm-long, cylindrical graphite (pure carbon) rod is inserted into an oxidizing atmosphere at 1145 k and 1.013 x 105 pa pressure. the oxidizing process is limited by the diffu- sion of oxygen counterflow to the carbon monoxide that is formed on the cylindrical surface.

im doing test rn im going with 2 but ill give answer if itss wrong,   : )
