Question

Unless otherwise instructed, you may use the periodic table in the Chemistry: Problems and Solutions book for this question.Which ion would represent the ion of an element from Group 2A?

Answer 1

An ion from Group 2A of the periodic table is known as an alkaline earth metal ion with a charge of +2. These ions have a charge of +2. The charge of an ion can be determined based on its group number on the periodic table. Group 2 elements form 2+ ions because they tend to lose two electrons to achieve a stable electron configuration.
