WebIons are formed as a result of this addition or removal of electrons from the atom. Negative ions, known as anions, form when an atom gains electrons and now has more electrons … WebSep 1, 2024 · Forming negative ions The outer shells of non-metal atoms gain electrons when they form ions: the ions formed are negative, because they have more electrons than protons. the ions formed have full outer shells. for groups 6 and 7, the number of electrons gained is equal to: 8 – group number.

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.
