For example, fluorine has seven valence electrons, so it is most likely to gain one electron to form an ion with a 1- charge. We can use this method to predict the charges of ions in ionic compounds.

One type of chemical bond is an ionic bond. Ionic bonds result from the attraction between oppositely charged ions. For example, sodium cations (positively charged ions) and chlorine anions (negatively charged ions) are connected via ionic bonds in sodium chloride, or table salt.
