MgCO3
Valence is determined by the periodic table of chemical elements of D. I. Mendeleev.
So, we look at the valence of each atom –
Mg = 24 (magnesium) (we have one atom, which means we multiply by 1)
C = 12 (carbon) (one atom)
O = 16 (oxygen) (three atoms, multiply 16 by 3 = 48)
O3 = 48
We add up the valence of each atom and so we find the total.
Those. Total valence = Mg + C + O3 = 24 + 12 + 48 = 84
