Because they're located on the very right of the Periodic Table, meaning that they have full outer shells. What atoms "want" in a reaction is to have full outer shells, so noble gases don't react with any other elements. Therefore the name "noble gases". Too noble to have any kind of contact with anyone else, understand? :)
A noble gas is one of the inert gases (helium, neon, argon, xenon, krypton, radon) which does not easily form compounds. At one time there were no noble gas compounds known but now xenon. krypton and radon compounds have been created.
They were called "noble" gases because like the nobility (kings, queens, dukes etc.) they stood aloof from the common chemicals
Other elements in their ground state have a network of bonding, which increases the melting and boiling points. Noble gases do not have bonds.
More info: In fact, most elements that do not have a bond network are gases. Exceptions: phosphorus, arsenic, sulfur, iodine, bromine. These have atoms bonded in clusters instead of a network, but the clusters are large enough so that electrons can form enough temporary dipoles to keep them all stuck together.
Noble gases have completely filled orbitals / energy levels. They generally have 8 valence electrons (helium has only 2) and have stable electronic configuration. Hence they are chemically inert and generally donot form compounds under normal conditions.
Argone
All noble gases - He, Ne, Ar, Kr, Xe - were used in lasers.
No, it is a noble gas
no because it only has one electron which makes it impossble to separate it
Radon is a noble gas and is radioactive.
argon, neon

In noble gas notation, you don't have to write the electron configuration up to that noble gas. You simply put the noble gas in brackets [noble gas] and then continue to write the electron configuration from that point. It just makes it shorter and easier to write electron configurations for elements with a lot of electrons.
No, it is a noble gas
Radon is a noble gas, which makes it a group 18 element.
no because it only has one electron which makes it impossble to separate it
Radon is a noble gas and is radioactive.
no. it is a molecule, not a noble gas
A noble gas is colorless.
Neon is a noble gas.
argon is a noble gas
