Metals of the first transition series have special properties which are different from those of groups I and II elements because they have partially filled

Answer Details

Metals of the first transition series have unique properties because they have partially filled D orbitals. Unlike groups I and II elements that have completely filled s orbitals, transition metals have partially filled d orbitals which makes them good conductors of electricity, have high melting and boiling points, are malleable and ductile, and are able to form compounds with different oxidation states. The partially filled d orbitals allow for the formation of complex ions and compounds, which can exhibit interesting and useful properties.
