How does calcium form an ion
WebHow is a calcium ion formed? Calcium, Ca Calcium is also in Group 2. It has two electrons in its outer shell. When these electrons are lost, a calcium ion, Ca 2 +, is formed. Why is … WebCalcium is an alkaline earth metal—Group 2 on the periodic table—so it forms ions with a 2+ charge. From our table, we know that hydroxide has the formula \text {OH}^- OH− and that it carries a 1- charge. We will need two hydroxide ions to exactly cancel the 2+ charge on \text {Ca}^ {2+} Ca2+.
