Properties of Transition Elements

Physical Properties of Transition Elements:

1. High boiling and melting pointThe temperature at which a solid changes its state to liquid at atmospheric pressure is called the melting point of that liquid. The melting point is usually defined as the point... More.

2. They are hard, dense, and lustrous.

3. Good conductors of heat and electricity.

4. They have high densities.

Characteristic Properties of Transition Elements:

The properties that are characteristic of transition elements and their compounds are as follows: 

1. Variable Oxidation State:

Transition metals exhibit variable oxidation states because the 4s and 3d electrons are available for bond formation. Most transition elements show a common oxidation state of +2 which corresponds to the removal of the 4s² electrons.

Manganese forms the highest oxidation state of +7 with the electronic configuration 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d⁵ .

Elements with variable oxidation states are typical transition elements, since scandium and zinc form only Sc³⁺ and Zn²⁺ respectively, they are not typical transition elements.
