WebJul 3, 2024 · Calcium in its most common state is a cation. It has a 2+ charge and thus has a net ratio of two more protons than electrons. Calcium is an important cation in the human body and its positive... 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+.

Here's how you'd figure this out. If you look at the periodic table, you'll see that calcium is in group 2. That means that it has two valence electrons that it must give up in order to be stable. WebThis results in a cation with 20 protons, 18 electrons, and a 2+ charge.
