Electrons are knocked off one of the atoms, and usually molecular bonds are lost as shared electrons drop in to fill the lower-shell vacancy. Eventually an electron is returned to return the loose ion to a neutral state. Eventually the molecule fragments form new bonds, either different than before (oxygen to ozone), or the same as before.
Noble gases do not react chemically with other noble gases.
It becomes unstable, so noble gases will not lose or gain electron
None of them have a negative charge. Or a positive charge. They can be ionized by high voltages, as (for example) neon is in a neon sign. However, neon doesn't have a monopoly on that, all of them exhibit the same behavior.

Gases, hence noble "gases"

Neutral gases do not; ionized gases do.
Noble gases do not normally form compounds.

The Group 18 elements are called the noble gases or sometimes inert gases. Wikipedia has information on the noble gases, and a link is provided.
it's not
Noble gases are chemically inert.
There are no metals in noble gases.All are gases in noble gases.
All noble gases are gases in their standard state
