Changes

: [[Transition Metal]]s can form several different [[charge]] [[ion]]s and these different [[charge]]s can determine the [[Physical Property|physical properties]] of the [[compound]]s they are in. Specifically this affects the [[colour]] of those [[compound]]s.

In [[compound]]s the [[charge]] of the [[Transition Metal]] [[ion]] is given in [[Roman Numeral]]s after the name of the [[metal]]

*Copper (II) Sulphate: +2 [[Ion]] of [[Copper]] giving the [[compound]] a blue colour.

*Manganese (II) Chloride: +2 [[Ion]] of [[Manganese]] giving the [[compound]] a pale pink colour.
