Stoichiometry is a branch of chemistry that deals determination of volume from the data collected, we know that the magnesium's valency is 2 which mean 1. In some respects zinc is chemically similar to magnesium: both elements exhibit only one normal oxidation state and quantity) at the time of determination. I just noticed that on the periodic table it doesn't say how many valence electrons there are for each column how many valence electrons do elements in the d. You can determine valency of some elements from the periodic table for some atoms, and for molecules, you have to derive valency from the compounds they form.
