Inert Gases don't readily react with other elements; Noble Gases are a specific group of inert gases in the periodic table's Group 18.
The noble gases are colourless, odourless, tasteless, nonflammable gases. They traditionally have been labeled Group 0 in the periodic table because for decades after their discovery it was believed that they could not bond to other atoms; that is, that their atoms could not combine with those...
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. ...
In chemistry, the noble gases refer to the chemical elements that belong to Group 18 of the periodic table. This family of elements can be found on the far right end of the periodic table, in the last column.Noble gasesare referred to as inert gases because they will not react with any...

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 ...
The last group of elements in the periodic table consists of the noble gases, which have solid phases in the fcc structure at low temperatures. The total energy plots give the fcc as the ground state for all these elements in agreement with experiment. These materials become metallic at large...
The atomic sizes of the noble gas elements increase from top to bottom in the Periodic Table, and the amount of energy needed to remove an electron from their outermost shell, the ionization energy, decreases in the same order. Within each period, however, the noble gases have the largest ...
