Noble gases are, for all intents and purposes, unreactive - there are a few noble gas compounds but you have to really work at it to convince noble gases to form bonds. Fluorine is an extremely reactive gas, hence it is not a noble gas. It is a halogen - the most reactive halogen of them all.
This gas is neon.

Fluorine is a name for the gas and the ion without the extra electron that fluorine will rip from any other (non-noble gas) element. F0 or F2 Fluoride is the name for the fluorine negatively charged ion. F-
