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

Learn what noble gases are, how they are classified, and what are their physical and chemical properties. Find out the names, symbols, and electronic configurations of the six noble gases: helium, neon, argon, krypton, xenon, and radon.
May 23, 2020 · Noble gases are the elements in group 18 of the periodic table with filled valence shells. They are mostly inert, colorless, odorless, and monatomic gases that can form compounds under extreme conditions.

May 17, 2024 · The noble gases—most often helium and argon, the least expensive—are used to provide chemically unreactive environments for such operations as cutting, welding, and refining of metals such as aluminum (atmospheric oxygen and, in some cases, nitrogen or carbon dioxide would react with the hot metal).
Jun 30, 2023 · The noble gases (Group 18) are located in the far right of the periodic table and were previously referred to as the "inert gases" due to the fact that their filled valence shells (octets) make them extremely nonreactive. The noble gases were characterized relatively late compared to other element groups.
