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.
Neon
because fluorine is highly electronegative element and reacts with the electron cloud of krypton and xenon

The element with a mass number of 19 could be fluorine, which is a halogen and a gas, but not a noble gas.

H2 + F2 -> 2HFhydrogen + fluorine -> hydrogen fluorideOne molecule of hydrogen reacts with one molecule of fluorine to produce two molecules of HF.
Hydrogen Fluoride. H2 + F2 ----> 2HF
