Question

why are p-block elements known as representative elements???

Priya G N · Accepted Answer

Not only p-block even s-block
elements are known as representative elements

For both s- and p-blocks, their
outer shells are not completely filled with electrons They follow
normal rules for filling the orbitals

These s- and p-block elements get
the nearest inert gas configuration by loosing or gaining of
electrons

In s- and p-block elements, all
the elements down the group have a relation of having same no of
electrons in their outer most shell and represents similar
electronic configuration Hence s- and p-blocks elements are known
as representative elements

Example: In s-block all group I elements have s1 configuration,
while in p-block all group III have ns2 np1
configurations
