The noble gases are used in excimer lasers, which are based on short-lived electronically excited molecules known as excimers. The excimers used for lasers may be noble gas dimers such as Ar 2, Kr 2 or Xe 2, or more commonly, the noble gas is combined with a halogen in excimers such as ArF, KrF, XeF, or XeCl. Ver mais 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 … Ver mais The noble gases have weak interatomic force, and consequently have very low melting and boiling points. They are all monatomic Ver mais The noble gases are colorless, odorless, tasteless, and nonflammable under standard conditions. They were once labeled group 0 in … Ver mais Noble gases have very low boiling and melting points, which makes them useful as cryogenic refrigerants.
