Which group on the periodic table has elements that are almost completely non-reactive?

Question:

Which group on the periodic table has elements that are almost completely non-reactive?

Periodic Table:

The tabular display of elements according to the atomic number arranged in a sequence is called the periodic table. This table comprises of s-block, p-block, d-block, and f-block elements.

Answer and Explanation: 1

The metals or elements that do not react with any other element or metal are referred to as non-reactive elements.

The elements that contain any unpaired electrons are reactive as they need an electron to complete their octet configuration. In contrast, the elements containing no unpaired electrons are non-reactive as their octet is occupied.


Group 18 in the periodic table is non-reactive as these elements have full filled s and p-orbital, and its general configuration is {eq}\rm n{s^2}n{p^6} {/eq}. This group is also referred to as Nobel gases or inert gases. He, Ne, Ar, Kr, Xe, and Rn all are non-reactive elements.


Thus, the non-reactive elements are group 18 elements.
