Gases whose outermost electron shells are completely filled with electrons. Such gases are extremely stable and it is difficult to coerce them to form compounds with other elements. There are six noble gasses: helium( ), neon, argon, krypton, xenon, and radon. This group of elements were originally known as the inert gasses, but in the early 1960s it was found to be possible to combine krypton, xenon, and radon with fluorine to create compounds. Although helium, neon, and argon continue to resist, there is an increasing trend to refer to this group of gasses as noble rather than inert.
any element from Group VIIIA of the periodic table; the and sublevels of their outermost energy level are filled (except helium with only 2 electrons in the 1); also known as inert gases because they are very unreactive.
one of a group of rare but extremely stable gases with low reaction rates (helium, neon, argon, krypton, xenon, radon).
A gaseous chemical element that does not readily enter into chemical combination with other elements.
any of the chemically inert gaseous elements of the helium group in the periodic table
One of the elements of Group 0 of the Periodic Table
Noble gas refers to any element of the group of six elements in group 18 of the periodic table. They are helium (He), neon (Ne), argon (Ar), krypton (Kr) , xenon (Xe), and radon (Rn). Unlike most elements, the noble gases are monoatomic. The atoms have stable configurations of electrons. Therefore, under normal conditions they do not form compounds with other elements. They were generally called inert gases until about 1962 when xenon tetrafluoride, XeF4, was produced in the laboratory. This was the first report of a stable compound of a noble gas with another single element.
Any of a group of rare gases that include helium, xenon, and sometimes radon and that exhibit great stability and extremely low reaction rates. They are often referred to as inert gases.
The noble gases are the elements in group 18 (Group 0 IUPAC Style) of the periodic table. It is also called helium family or neon family. They are the most stable due to having the maximum number of valence electrons their outer shell can hold.
Noble Gas is an experimental music and sound collage band which originated in Los angeles in the late 1970s. The members have been involved in the arts and music for a combined of nearly 100 years.They took their name from the 18th Group of the Periodic Table of elements.
