Noble gases.
Group 18 or Noble gases.
Group 18 on the periodic table contains the noble gases, also known as the inert gases. This family includes helium, neon, argon, krypton, xenon, and radon. They are colorless, odorless gases with very low reactivity.
Argon belongs to the noble gas family, also known as Group 18 or Group 0 on the periodic table. These elements are known for their low reactivity and full outer electron shells.
Old textbooks usually gave the noble gases group 0., although some did call it group VIIIA.
The noble gases family in Group 18 have a filled outer energy level, making them very stable and unreactive.
The Group 0 elements are called the noble gases. These are the six gases that are almost completely inert. Since they do not lose or gain any electrons, their valence is 0.
Noble gases have a 0 oxidation number because they have a full valence shell of electrons, making them stable and unreactive.
Group-17 is the nearest neighbor to the noble gases in the periodic table.
Helium belongs in the noble gas family, which is group 18 (VIIIA or 0) on the periodic table. It is a noble gas because its valence shell is filled (with two electrons) and it is completely non-reactive.
In chemistry the Inert Group are the Noble Gases. So called be cause they do not react with anything. The gases are Helium, Neon, Argon, Krypton, Xenon, Radon.
All the elements in the Inert Gases family (exc. Radon) are highly unreactive. The Inert Gases family occupies Group 18(0) of the Periodic Table. They each have 8 electrons in the outer shell. The Inert Gases Group contains;HeliumNeonArgonKryptonXenonRADON
