Any of the six gases helium, neon, argon, krypton, xenon, and radon. Because the outermost electron shell of atoms of these gases is full, they do not react chemically with other substances except under certain special conditions. Also calledinert gas. SeePeriodic Table. ...
Noble gases, also called inert gases belong to the group 18 of the periodic table. Elements belonging to this group are helium, neon, argon, krypton, xenon, and radon. This piece highlights the electron configurations of these noble gases....

For this reason, they were called inert gases. They were also clustered under Group 0 in the old periodic table because scientists believed that the gases have zero valence electrons in their outer shell. This was later proven to be untrue when some noble gas compounds were discovered.3. Th...

The meaning of NOBLE GAS is any of a group of rare gases that include helium, neon, argon, krypton, xenon, and usually radon and that exhibit great stability and extremely low reaction rates —called also inert gas.
(See also chemical bonding: Bonds between atoms.) Screened from the nucleus by intervening electrons, the outer (valence) electrons of the atoms of the heavier noble gases are held less firmly and can be removed (ionized) more easily from the atoms than can the electrons of the lighter ...
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 ...
Do noble gases react with air? They are called noble gases because they are so majestic that, in general,they don't react with anything. For this reason they are also known as inert gases. The noble gases are present in the atmosphere in small amounts: 0.934% Argon. ...
The noble gases (historically also the inert gases; sometimes referred to as aerogens[1]) are the naturally occurring members of group 18 of the periodic table: helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn). Under standard conditions, these chemical ...
