Lithium is a metal with an oxidation number of 1+ and oxygen is a nonmetal with an oxidation number of 2-. which chemical formula represents the compound formed by these two elements? a. li2o b. li3o c. lio d. lio2

Option (a) is the correct answer.

Explanation:

According to the cross multiplication method, charges present on the combining atoms cross multiply with the atoms in order to keep the molecule formed neutral.

For example, oxidation number of lithium is +1 and oxidation number of oxygen is -2.

So, when both of them chemically combine with each other then lithium atom will get multiplied by 2 whereas oxygen atom will get multiplied by 1.

Therefore, we can conclude that formula of this chemical compound will be .

the old alchemists made significant contributions to science even though there starting premises were off a bit. their conclusions after failure would steer them into better directions for investigation. science is no more than close observation and the initial mistakes result in rethinking and retrying experiments.
