Transition Metals
| Physical Properties (compared to Group 1) | Chemical Properties (compared to Group 1) |
| Much harder | Much less reactive |
| Higher tensile strength | Many have excellent corrosion resistance |
| Higher density | Show more than one valency (e.g. Fe2+ or Fe3+) |
| Higher melting point and boiling point | Them and their compounds are useful catalysts |
| Many of their compounds are coloured | Some are strongly magnetic |
