In the periodic table, periods are horizontal rows and groups (also called families) are vertical columns. Group 2 contains the alkaline earth metals, including beryllium (Be), magnesium (Mg), and calcium (Ca). These elements have two valence electrons and tend to form ionic compounds with a +2 charge. In period 4, these elements are located in the fourth row of the periodic table. The only element listed in the answer choices that fits this description is calcium (Ca), so the correct answer is choice C.
