Properties of d block elements 👩‍🔬

 Physical properties:

1.     All d block elements are lustrous and shining.
2. They are hard and have high density.
3. Have high melting and boiling points.
4. Have high tensile strength and malleability.
5. Can form alloys with transition and non transition elements.
6. Many metals and their compounds are paramagnetic.
7. Most of the metals are efficient catalysts. 

Chemical properties:

1.   All d block elements are electropositive metals.
2. They exhibit variable valencies and form colored salts and complexes.
3. They are good reducing agents.
4. They form insoluble oxides and hydroxides.
5. Iron, cobalt , copper,  molybdeum and zinc are biologically important metals.
6. Catalyse  biological reactions.
