The oxidation number illustrates the number of electrons that a particular atom has partially/completely donated/accepted. +2 stands for donation of two electrons such as magnesium in magnesium salts. The oxidation number of -2 stands for obtaining two electrons such as an oxygen atom in an oxide.

What do the oxidation number 2 imply?

The oxidation number of a chemical tells how many electrons it will gain or lose in a reaction. A positive oxidation number means that it will lose electrons, and a negative means it will gain them. A chemical with an oxidation number of 2+ would usually lose 2 electrons in a reaction.All of the Alkali earth metals (second column of the periodic table) have an oxidation number of 2+.
