Question

What are transition elements? Write any four characteristic properties of transition metals.

Answer 1

Transition elements : The elements which have plenty filled d - subshells are known as d - block elements . These elements are lying between S and P - block elements. They represnt transition transition (change) in properties from strongly electropositive and metallic character of S - block elements to electronegative and non-metallic character of P - block elements, i.e. their properties are inter-mediate to those of S - block and P - block elements.
Four characteristic properties of transition metals.

1. They are hard, heavy and less reactive metals.
2. They show variable valencies.\
3. They give coloured ions.
4. They have high tendency to form complex compounds.
