Answer 2

Answer:

As lithium oxide is a neutral compound, its overall oxidation number is zero. One of the rules in determining the oxidation numbers is that the oxidation number of oxygen is -2 in most cases.

The oxidation number of lithium is then calculated to be +1 in Li2o

This is confirmed by one rule that states the oxidation number of alkali metals (metals of the group one of the periodic table) is +1.
