The ion that would represent the ion of an element from Group 2A is A superscript 2 plus (A²+).

GROUP 2 ELEMENTS:

Group 2 elements are elements that have two valence electrons in their outermost shell.

Group 2 elements include Calcium, Beryllium, Magnesium, etc. They donate two electrons when involved in a reaction to have a stable structure.

Group 2 elements become positively charged (cations) when they lose two electrons, hence, they have an ion of +2.
