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 helium … Zobacz więcej 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 … Zobacz więcej 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 … Zobacz więcej 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 Zobacz więcej 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 … Zobacz więcej 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 … Zobacz więcej The color of gas discharge emission depends on several factors, including the following: • discharge … Zobacz więcej • Noble gas (data page), for extended tables of physical properties. • Noble metal, for metals that are resistant to corrosion or oxidation.

Thanks to excitation, shells of the atoms aren't closed and they react, but very quickly they lose energy and become separate atoms. lawyers on salt spring island
