Inert gas意思

"Inert gas" is a term used in chemistry to describe a gas that does not react with other substances. The word "inert" means not reactive or inactive. In the context of chemistry, inert gases are those that do not easily combine with other elements or compounds to form new substances.

The most commonly known inert gases are the noble gases, which include helium, neon, argon, krypton, xenon, and radon. These elements are all in the Group 18 of the periodic table, also known as the "noble gas group." They have full valence electron shells, which makes them very stable and unlikely to react with other elements.

However, it's important to note that the term "inert gas" is not always used in a strict scientific sense, and some gases that are not noble gases may also be referred to as inert under certain conditions. For example, nitrogen gas (N2) is a common component of air and is generally considered inert and non-reactive at standard temperature and pressure.
