The noble gases (historically the inert gases, sometimes referred to as aerogens[1]) are the members of group 18 of the periodic table: helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), radon …

Learn about the properties of inert gases like argon and nitrogen, including their resistance to oxidation and use in creating stable environments.

Nov 22, 2025 · noble gas, any of the seven chemical elements that make up Group 18 (VIIIa) of the periodic table. The elements are helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), radon …

Aug 29, 2025 · Inert gases are a group of chemical elements known for their stability and non-reactivity. They rarely participate in chemical reactions, making them valuable in applications where unwanted …

Sep 17, 2025 · Inert gases, also known as noble gases, are a group of elements that are very stable and do not react with other elements. The most common inert gases are helium, neon, argon, krypton, …

May 30, 2019 · Noble gases are the least reactive chemical elements. They are nearly inert because the atoms have a full valence electron shell, with little tendency to accept or donate electrons to form …

Aug 27, 2025 · An inert gas is a non-reactive gas, meaning it doesn’t have a chemical reaction with any other gas or substance under normal conditions. These gases are also known as noble gases, and …

Aug 11, 2025 · An inert gas is a non-reactive gas that doesn’t readily undergo chemical reactions under normal conditions because of its stable electron configuration. This non-reactivity makes inert gases …

Feb 3, 2015 · Inert gases are the elements in which the outermost electron shells are completely filled with electrons, so they don’t participate in any chemical combination in ordinary conditions.

The noble gases often do not react with many substances and have been historically called inert gases. Generally, inert gases are used to prevent unwanted chemical reactions which degrade a sample.
