What are the common chemical properties of d-block elements?
✓

Answer

The common chemical properties of the d-block elements are :
  • All d-block elements are electropositive metals.
  • They exhibit variable oxidation states and form coloured salts and complexes.
  • They are good reducing agents.
  • They form insoluble oxides and hydroxides.
  • Iron, cobalt, copper, molybdenum and zinc are biologically important metals.
  • They catalyse biological reactions.
