Transition metals have the following properties: 1) All are
metals.
2) Most are harder,
more brittle, have higher melting
points and boiling points, and higher
heats of vaporization than
non-transition
metals (group 1A, 2A).
3) Their ions and
their cmpds are usually coloured. 4) They form many complex ions.
5) They exhibit multiple
oxidation states
