They have similar properties such as being odourless, colourless and have very low reactivity. group 0 - noble gases. While groups (columns) of the periodic table are sometimes named after their lighter member (as in "the oxygen group" for group 16), the term iron group does not mean "group 8". • The first compound of a noble gas, XePtF 6, was made in 1962. Why are group 8 elements, in the periodic table, called Noble Gases? Helium. This group consist of six elements, namely Helium, Neon, Argon, Kripton, Xenon and Radon. - what % of the atmosphere do they make up? This video resource, taken from the CHRISTMAS LECTURES 2012 contains an overview of the Group 8 (18) elements; the Noble Gases. Xénon. -And could you name 1 use for each? They are all inert, monatomic, colourless gases. The six noble gases that occur naturally are helium (He), Neon (Ne), Argon (Ar), Krypton (Kr), Xenon (Xe), and Radon (Rn).
