Q.49:- Give the electronic configuration of the transition elements. Write their four important characteristics.
The d-block elements are known as transition elements.
Electronic configuration =(n – 1) d1-10 ns1 -2
Characteristics of d-block elements:
- They show variable oxidation states.
- Their compounds are generally paramagnetic in nature.
- Most of the transition elements form coloured compounds.
- They are all metals with high melting and boiling points.
