Common properties of d block elements

Physical properties

• i. All d block elements are lustrous and shining.
• ii. They are hard and have high density.
• iii. Have high melting and boiling points.
• iv. Are good electrical and thermal conductors.
• v. Have high tensile strength and malleability.
• vi. Can form alloys with transition and non transition elements.
• vii. Many metals and their compounds are paramagnetic.
• viii. Most of the metals are efficient catalysts.

Chemical properties

• i. All d block elements are electropositive metals.
• ii. They exhibit variable valencies and form colored salts and complexes.
• iii. They are good reducing agents.
• iv. They form insoluble oxides and hydroxides.
• v. Iron, cobalt, copper, molybdenum and zinc are biologically important metals
• vi. catalyse biological reactions.
