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.

For binary ionic compounds (ionic compounds that contain only two types of elements), the compounds are named by writing the name of the cation first followed by the name of the anion. For example, KCl, an ionic compound that contains K⁺ and Cl⁻ ions, is named potassium chloride. video https://cdn.kastatic.org/googleusercontent/F9fhxeAzbl5tczOC_KxI5UnfufCJyVdO9qXgu-Rltqyf00aQlHvx_6KjnT27peERAhBSPipQTUL_5Zz001iLpgdW Naming ions and ionic compounds Ionic compounds are neutral compounds made up of positively charged ions called cations and negatively charged ions called anions.
