- The noble gases (historically the inert gases, sometimes referred to as aerogens) 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).

Helium, neon, argon, krypton, xenon, and radon are inert gases. Inert gas systems on ships. Inert gas is produced on board crude oil carriers (above 8,000 tonnes from Jan 1, 2016) by burning kerosene in a dedicated inert gas generator.
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.
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 term “noble gas” comes from a translation of the German word Edelgas, which means noble gas. German chemist Hugo Erdmann coined the phrase in 1898. Like a nobleman might consider it undignified to associate with commoners, noble gases tend not to react with other elements. Other names for noble gases include rare gases, inert gases, and aerogen...
There are either six or seven noble gas elements, depending on whether or not you include element 118, oganesson. 1. Helium(He) 2. Neon(Ne) 3. Argon(Ar) 4. Krypton(Kr) 5. Xenon(Xe) 6. Radon(Rn) 7. Oganesson(Og) The first six elements occur naturally. Radon and oganesson are radioactive elements. Oganesson is a man-made (synthetic) element that does...
Elements in the noble gas group share common chemical and physical properties: 1. Behave as nearly ideal gasesunder standard conditions 2. Monatomic gases at room temperature 3. Fairly nonreactive 4. Complete outer electron or valence shell (oxidation number = 0) 5. High ionization energies 6. Very low electronegativity values 7. Low melting points...
The most common misconception about the noble gases is that they cannot form chemical bonds and compounds. While their atoms normally have filled valence shells, it’s possible to remove one or more electrons or (less commonly) add electrons. Under certain conditions, the noble gases can form diatomic gases, clathrates, fluorides, chlorides, metal c...
The noble gases have several important uses. They are used as an inert atmosphere to protect specimens and minimize chemical reactions. Their low melting and boiling points make them useful as refrigerants. The noble gases are important in lighting applications, such as high-intensity lamps, neon lights, car headlamps, and excimer lasers. Helium is...
Neon, argon, krypton, and xenon come from fractional distillation of liquefied air. The primary source of helium is cryogenic separation of natural gas. Radon comes from radioactive decay of radium, thorium, uranium, and other heavy radioactive elements. Oganesson is a man-made element synthesized by striking a target with accelerated particles. In...

When the members of the group were discovered and identified, they were thought to be exceedingly rare, as well as chemically inert, and therefore were called the rare or inert gases.
A noble gas configuration of an atom consists of the elemental symbol of the last noble gas prior to that atom, followed by the configuration of the remaining electrons.
