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 p-block elements
They consist of elements of groups 13 – 18.
They involve metals, non-metals and metalloids.
They show variable oxidation state.
They are electronegative.

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.

Properties of f-block elements
They are also called “Inner Transition Elements”.4f series elements are called lanthanoids.
5f series elements are called actinoids.
They form coloured ions and complexes.
They act as catalysts.
They show variable oxidation state.The elements after Uranium are called Transuranium Elements.
