An inert gas is a gas that does not readily undergo chemical reactions with other chemical substances and therefore does not readily form chemical compounds.
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 (Rn) and, in some cases, oganesson (Og).

The noble gases, also known as the inert gases or rare gases, are located in Group VIII or International Union of Pure and Applied Chemistry (IUPAC) group 18 of the periodic table. This is the column of elements along the far right side of the periodic table. This group is a subset of the nonmetals. Collectively, the elements are also called the he...
The noble gases are relatively nonreactive. In fact, they are the least reactive elements on the periodic table. This is because they have a complete valence shell. They have little tendency to gain or lose electrons. In 1898, Hugo Erdmann coined the phrase "noble gas" to reflect the low reactivity of these elements, in much the same way as the nob...
The noble gases are used to form inert atmospheres, typically for arc welding, to protect specimens, and to deter chemical reactions. The elements are used in lamps, such as neon lights and krypton headlamps, and in lasers. Helium is used in balloons, for deep-sea diving air tanks, and to cool superconducting magnets.
Although the noble gases have been called the rare gases, they aren't particularly uncommon on Earth or in the universe. In fact, argon is the 3rd or 4th most abundant gas in the atmosphere(1.3 percent by mass or 0.94 percent by volume), while neon, krypton, helium, and xenon are notable trace elements. For a long time, many people believed the no...
Neon, argon, krypton, and xenon all are found in air and are obtained by liquefying it and performing fractional distillation. The major source of helium is from the cryogenic separation of natural gas. Radon, a radioactive noble gas, is produced from the radioactive decay of heavier elements, including radium, thorium, and uranium. Element 118 is ...

May 23, 2020 · The noble gases are the elements in group 18 on the periodic table. Atoms of these elements have filled valence electron shells, making them relatively inert, colorless, odorless, monatomic gases at room temperature and pressure.
Oct 23, 2024 · Quick Reference. Syn: noble gas. Helium, neon, argon, krypton, xenon, and radon, all of which occur in trace amounts in the atmosphere, and all of which share the quality of being difficult to combine chemically with other elements or chemical compounds, thus the name “inert,” although this name is discouraged in favor of “noble ...
Jun 30, 2023 · Argon also creates an inert gas shield during welding, flushes out melted metals to eliminate porosity in casting, and provides an oxygen- and nitrogen-free environment for annealing and rolling metals and alloys.
