WebA positive or negative number assigned to an element to show its combining ability in a compound. How many electrons an atom has gained, lost, or shared when bonding with … 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.
