Question

Valency of
oxygen and magnesium is 2. Is there any difference on both valencies?
​

Answer 1

Answer:

Yes for both o2 and MG have different valancy

Answer 2

Answer:

yes,

although Magnesium and Oxygen both have a valence of two they are very difference chemically because the valence number of Mg is +2 and the valence number of O is -2 the valence number indicates the configuration of the stable ion.
