lonic Bonds Which compounds have ionic bonds? Cation: formed from active metal atoms, ( Group IA and lIA),e.g. Li, Na, Mg, K, Ca Anion: formed from active non-metal atoms, (Group VIA and VIIA), e.gO, F, S, Cl, Br, I How to represent ionic bonds? Cation and anions are written in brackets with the outmost shell of electrons and chargesIonic Bonds  Which compounds have ionic bonds?  Cation: formed from active metal atoms, (Group IA and IIA), e.g. Li, Na, Mg, K, Ca, …  Anion: formed from active non-metal atoms, (Group VIA and VIIA), e.g. O, F, S, Cl, Br, I, …  How to represent ionic bonds?  Cation and anions are written in brackets, with the outmost shell of electrons and charges. 4
