s - block and p - block elements except 18th group elements are sometimes called as `Representative elements' based on their abundant availability in the nature. Is it justified? Why?

Question

Philoid · Accepted Answer

The elements of s and p-block except noble gas are called as representative elements because:

i. The outer shells of the elements of s and p-block are not completely filled.

ii. They achieve noble gas configuration by losing or gaining electrons.

iii. As a result, they are chemically inert active.

iv. The elements down the group represent have same number of electrons in the outermost shell.

v. They have same electronic configuration.

vi. Hence, the s and p-block elements are called representative elements.
