What group in the periodic table typically has a +2 charge?

The group in the periodic table that typically has a +2 charge is group IIA, also known as the alkaline earth metals. Elements in this group, which includes magnesium (Mg), calcium (Ca), and barium (Ba), have two valence electrons. When they undergo chemical reactions, they tend to lose these two electrons to achieve a stable electron configuration, which results in a +2 positive charge. This behavior is characteristic of their reactivity and is reflected in the chemical compounds they form, where they typically exhibit the +2 oxidation state.

The other groups listed do not typically exhibit a +2 charge. For instance, group IVB can have varying charges, including +4 and +2, depending on the element and the compound formed. Group IB mainly contains elements like gold, silver, and copper, which typically form +1 and other oxidation states but are not predominantly found in the +2 state. Group IA, which consists of alkali metals, typically has a +1 charge due to the loss of a single valence electron. Therefore, IIA is clearly the group that aligns with a consistent +2 charge in its elements.
