Properties of s-block elements
They consist of alkali and alkaline earth metals.They are metals and are thus electropositive.
They are highly reactive .
They are predominantly ionic.
They have low ionization enthalpies.

Properties of d-block elements
They consist of elements of group 3 – 12.
They are called transition metals.
They form coloured ions .
They act as catalysts.
They form complexes.
They show variable oxidation state.
