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 … WebOct 23, 2024 · Negative ions can also be formed by chemical reactions. For instance, when hydrochloric acid (HCl) dissolves in water, it forms H+ and Cl- ions. The H+ ions are positive because they’ve lost an electron; the Cl- ions are negative because they’ve gained one. Finally, some materials naturally attract electrons more than others do.
