WebMost atoms, however, can either gain or lose electrons; when they do so, the number of electrons becomes different from the number of protons in the nucleus. The resulting charged species is called an ion. Cations and anions Web(a) magnesium (Mg) (b) aluminum (Al) (c) bromine (Br) For example, oxygen forms ionic compounds as an anion with -2 charge because it needs to gain two electrons to have the same electron configuration as neon. Gallium, on the other hand, has a +3 charge because it needs to lose three electrons to have the same electron configuration as argon.

The Octet Rule - Chemistry LibreTexts

WebWhen forming ions, elements typically gain or lose the minimum number of electrons necessary to achieve a full octet. 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.
