The noble gas (Ng) elements have a rich reaction chemistry despite having a filled valence shell that would indicate otherwise. Halide compounds, usually with fluorine, and various oxides are common. There is also a growing class of carbon and nitrogen derivatives. A wide range of neutral and ...
In chemistry, the noble gases are a set of chemical elements that share similar characteristics and properties. There are six naturally occurring noble gasses, which are helium, neon, argon, krypton, xenon, and radon.Answer and Explanation: ...
atomic number 2,He,helium- a very light colorless element that is one of the six inert gasses; the most difficult gas to liquefy; occurs in economically extractable amounts in certain natural gases (as those found in Texas and Kansas) ...

and radon. The low chemical activity of the inert gases is due to the fact that their outermost, or valence, electron shell is complete, containing two electrons in the case of helium and eight in the remaining cases. The inert gases are sometimes called the rare gases, although argon is ...

to galactic cosmic rays as calculated from the10Be activity and from the low amounts of cosmic-ray-produced noble gases. The Zhaodong chondrite contains large amounts of80Kr and82Kr produced by neutron capture of bromine. From the high slowing down density for neutrons we derive a pre...
The current model of the atom is the quantum mechanical model. In this model, each element has a unique electron configuration. Noble gases are the family of elements that are nonreactive because their valence electrons are full. Answer and Explanation:1 ...
