Hint :A gas that does not undergo chemical reactions under a series of conditions is known as an inactive gas. The noble gases, also known as inert gases, are gases that do not react with certain substances. Inactive gases are used commonly to prevent unintended chemical reactions damaging a sample.
Complete Step By Step Answer:
Helium, neon, argon, krypton, xenon, and radon are among the group $18$ elements. Noble gases and inert gases are terms used to describe them. The general configuration of the valence shell is $n{s^2}n{p^6}$. In the atmosphere, both of these elements exist in a free state. Gases that are colorless, tasteless, and odourless. Their melting and boiling points are both tiny. They have a high ionisation enthalpy and a high positive electron gain enthalpy.
The arrangement of electrons in orbit around the nucleus of an atom determines chemical properties entirely. The outermost electrons are transferred through the different substances involved in all chemical reactions. The most stable electronic structure is found when an atom's outermost shell contains the maximum number of electrons it can support.
If the number of atoms in a noble gas increases, its abundance decreases. Except for hydrogen, helium is the most abundant element in the universe. Except for helium and radon, all of the noble gases are found in the Earth's atmosphere, and their primary commercial source is air, which they acquire by liquefaction and fractional distillation. The majority of helium is commercially extracted from natural gas wells. Radon typically is isolated as a result of the radioactive decomposition of radium compounds. Radium atoms' nuclei decay naturally, releasing energy and particles, including helium nuclei (alpha particles) and radon atoms.
Note :
Because of their natural abundance ($78.3$ percent ${N_2}$, $1$ percent $Ar$ in air) and low relative cost, purified argon and nitrogen gases are most commonly used as inert gases.
