Question

The 's' and 'p' blocks elements called representative elements.
If true enter 1, else enter 0

Answer 1

Because valence electrons represent group.

For example in case of alkali and alkaline earth elements they have one and two electrons in their valence shell they are in first and second group respectively.

Valence electrons represent the group number (except zero group).

Elements in which all the inner shells are complete but outer shell is incomplete is known as representative elements i.e Those elements which have less than 8 electrons in outermost shell are representative.

s and p block elements except inert gas is known as representative elements.
