In chemistry and alchemy, the word noble has long signified the reluctance of metals, such as gold and platinum, to undergo chemical reaction; it applies in the same sense to the group of gases covered here. The abundances of the noble gases decrease as their atomic numbers increase. Helium...

Noble Gases, being a subset of Inert Gases, share the characteristic of being unreactive, but they have their unique position in the periodic table. 10 One might encounter Inert Gases outside of the Noble Gases group. For instance, nitrogen (N2) is often considered an inert gas under ...
Noble gases have similar physical properties, which is why they are found in a group together.Physical propertiesrefer to the physical characteristics of an element, such as their boiling point, melting point, or solubility. In general, noble gases' physical properties include having a low boiling...

Synonyms Rare gases Definition The noble gases are a group of chemical elements with a very low chemical reactivity. In most natural conditions, they cannot form chemical compounds and their abundances and isotopic ratios are only affected by physical processes such as phase changes, kinetic effects...
Some of the groups have special names, like the alkali metals (group 1), alkaline earth metals (group 2), halogens (group 17), and noble gases (group 18). Groups 3 through 12 refer to the transition metals. The rows of the periodic table are called periods, for which the elements al...
