Helium is from the Greek word 'helios' meaning 'sun'; the element was given this name because of its yellow appearance.
Krypton comes from the word kryptos, which is Greek for "hidden one".
The name neon comes from the Greek neo, meaning new. Neon was given this name when it was discovered as a new element in 1898.
Although I'm not sure of this, but I think xenon means "the first"
They are already balanced. They have a full outer shell.
gases! you spelled it! as long as you mean gas as in air... :)
Means to trade gases with another cell to make it develop of a form to make it larger
Noble gases - the rest are Helium, Neon, Argon, Krypton, Xenon, and RADON.

Good guess, poor grammar.
They are already balanced. They have a full outer shell.
The nobles gases are the elements located on the very right of the periodic table. The elements are Helium, Neon, Argon, Krypton, Xenon and Radon. The common thing with the noble gases is that they have full outer shells, and don't react with any elements.
Nobles gases like argon, neon....
Helium, neon, argon are used because they are chemically inactive.

Noble Gases have an 'octet' which is a completely filled outer energy level with 8 electrons, except for Helium which has 2 valence electrons. This makes these gases in group 18 very stable.

noble gases are of very importance in our daily life as we make conclusions about the other valence shell completion of other elements by knowing the noble gases valence electronic configuration
Do you mean in ancient Egypt ?
