The resulting anion, Cl, is called the chloride ion; note the slight change in the suffix (-ide instead of -ine) to create the name of this anion. In cases where an atom has three or fewer valence electrons, the atom may lose those valence electrons quite easily until what remains is a lower shell that contains an octet. Cations have several unique properties and practical uses, and they are important in many areas of science and industry. For example, fluorine has seven valence electrons, so it is most likely to gain one electron to form an ion with a 1- charge.
