Explain magnetic behaviour of transition elements.

Transition element and their compounds exhibit paramagnetic behaviour and transition metals have high melting points. Explain.

Explain metallic character in transition metals.

Lanthanoids are much more paramagnetic than transition elements. Explain.

Explain the dual behaviour of matter.
