            The Transition metals are generally hard, strong metals with high melting and boiling points;  they are also usually electropositive. That is, they react by tending to lose, rather than gain, electrons.  Certain unique properties of the transition elements are related to their d subshell electrons. These properties include variable oxidation states, formation of brightly coloured compounds, tendency to form many complexes, and ferromagnetism and paramagnetism.
