Description

Common ions and their charges Group 1 ions have a +1 charge Group 2 ions have a +2 charge Group 13 ions have a +3 charge Cations take the name of the element, anions take the name of the element with an –ide suffix. Eg sodium + chlorine → sodium chloride Other important cations Mn2+ manganese(II) 2+ Fe iron(II) Fe3+ iron(III) 2+ Co cobalt(II) Co3+ cobalt(III) Ni2+ nickel(II) + Cu copper(I)

Zn2+ Ag+ Sn2+ Sn4+ Pb2+ Pb4+ Cu2+

zinc silver tin(II) tin(IV) lead(II) lead(IV) copper(II)
