Scandium forms no coloured ionis, yet it is regarded as a transition e – InterviewSolution

1.	Scandium forms no coloured ionis, yet it is regarded as a transition elements. Explain why ?
Answer» Solution :Scandium in the ground state has ONE ELECTRON int eh 3d-subshell . HENCE,it is regarded as a transitio elements. However, in its common oxidation state `+3`, it has no electron in 3dsusshell `( 3d^(0))` .Hence, it does not FORM coloured ion.
