Question

write the Common properties of d block elements​

Answer 1

$\huge\boxed{\fcolorbox{blue}{yellow}{Answer :-}}$

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.

Differences :

Although most properties exhibited by d block elements are similar, the elements of first row differ from second and third rows in stabilization of higher oxidation states in their compounds.
