An inert gas is known as what?

Explanation:
An inert gas is called a noble gas because these gases are very unreactive due to their full outer electron shells. They sit in Group 18 of the periodic table and include helium, neon, argon, krypton, xenon, and radon. That stability makes them ideal for creating an inert atmosphere that protects materials from oxidation or unwanted chemical reactions in environmental management contexts, such as preserving samples, packaging, or controlled processes. The other options don’t describe a type of gas: minerals are solid substances, a niche is an ecological role or habitat, and mulch is material spread on soil.
