Final answer:
The net charge of calcium fluoride (CaF2) is 0. One Ca2+ ion is balanced by two F- ions, resulting in a neutral ionic compound.
Step-by-step explanation:
The net charge of the ionic compound calcium fluoride is 0. Calcium typically has a 2+ charge when it forms a cation. Fluoride ions have a 1- charge each. In calcium fluoride (CaF2), one calcium ion (Ca2+) pairs with two fluoride ions (2 F-) to neutralize the overall charge. The chemical formula shows us that there are twice as many fluoride ions as calcium ions, providing a total negative charge of -2, which balances the +2 charge of calcium. Therefore, the compound has no net charge, which is typical for stable ionic compounds.
