Metals form this ion
WebMetal atoms lose electrons from their outer shell when they form ions: the ions are positive, because they have more protons than electrons the ions formed have full outer … WebBecause transition metal ions are small they have a strong electric field around them that attracts electron-rich species. Species that have a lone pair available to donate can form dative covalent bonds to the transition metal ion. We call such species ligands.
