http://en.wikipedia.org/wiki/Noble_gas The noble gasesare a group of chemical elements with very similar properties: under standard conditions, they are all odorless, colorless, monatomic gases, with a very low chemical reactivity. They are placed in group 18 (8A) of the Periodic Table (previously known as group 0). The six noble gases that occur naturally are helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and the radioactive radon (Rn). So far, three atoms of the next member of the group, ununoctium (Uuo) have been synthesized in a supercollider, but very little is known of that element's properties because of the tiny amount produced and its short half-life. http://www.webelements.com/
The noble gases are inert elements, which means they do not readily react with other elements to form compounds. This family includes helium, neon, argon, krypton, xenon, and radon.
Helium is a gas which is very light. It is the second lightest element in the universe. Helium was discovered in 1986. William Ramsay confirmed it was helium. Helium remains as gas up to 25c (77f). Helium has no taste or no color. Helium doesn't combine with other elements. It is a by product of the reaction of hydrogen in the sun.
Helium shares the most characteristics with neon because both elements are in the same group on the periodic table (Noble Gases). They both have a full outer electron shell, making them stable and nonreactive.

nobel gasses
Helium is a member of the noble gas family of elements. The elements of this family do NOT usually form compounds with other elements.
Elements in the same family, or group will contain the same number of valence electrons and have many similar characteristics.

Helium, Xenon, Neon, Krypton, and Radon.
Lithium, sodium and potassium are all in the first family.
Uranium is a member of the actinoids family. These chemical elements are:- they are considered frequently transition metals- they are radioactive elements- some are artificial elements- they have variable valence
Each family of elements has its own set of characteristics that each of the elements possess.

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.
