They belong to the 18th group of the periodic table. There are a total of six noble gases found in nature. These are helium, neon, argon, krypton, xenon, and radon. They are also present in the atmosphere in traces. These gases are generally denoted as.

The noble gases (historically also the inert gases; sometimes referred to as aerogens ) make up a class of chemical elements with similar properties; under standard conditions, they are all odorless, colorless, monatomic gases with very low chemical reactivity. The six naturally occurring noble gases are … Visa mer Noble gas is translated from the German noun Edelgas, first used in 1898 by Hugo Erdmann to indicate their extremely low level of reactivity. The name makes an analogy to the term "noble metals", which also have low … Visa mer The noble gases are colorless, odorless, tasteless, and nonflammable under standard conditions. They were once labeled group 0 in the periodic table because it was believed they had a valence of zero, meaning their atoms cannot combine with … Visa mer Noble gases have very low boiling and melting points, which makes them useful as cryogenic refrigerants. In particular, liquid helium, which boils at 4.2 K (−268.95 °C; −452.11 °F), is used for superconducting magnets, such as those needed in nuclear magnetic resonance imaging Visa mer The noble gases have weak interatomic force, and consequently have very low melting and boiling points. They are all monatomic gases under standard conditions, including the elements with larger atomic masses than many normally solid elements. Helium … Visa mer The abundances of the noble gases in the universe decrease as their atomic numbers increase. Helium is the most common element in the universe after hydrogen, with a mass fraction of about 24%. Most of the helium in the universe was formed during Big Bang nucleosynthesis Visa mer The color of gas discharge emission depends on several factors, including the following: • discharge … Visa mer • Noble gas (data page), for extended tables of physical properties. • Noble metal, for metals that are resistant to corrosion or oxidation. • Inert gas, for any gas that is not reactive under normal circumstances.
