Because before about 1950, the noble gases were not known to form any chemical compounds.
Nobel gases are also called inert gases because of their reluctance to combine with other substances.
Inert gases
No,they are not active.They are inert gases.
Noble gases are also called inert gases because they tend to be chemically nonreactive due to their stable electron configurations.
These elements are Nobel Gases in group 18.
Noble gases used to be called inert gases because until the 1960's no chemical compounds of a noble gas had been made hence they were believed to be completely inert. Now compounds of argon, xenon radon have been made. These are all very reactive. Compounds of helium and neon have not yet been made.
Inert gases can also be called noble gases. An example is Helium.

Noble Gases
Inert gases are the noble gases (He, Ne, Ar, Kr, Xe, and Rn). They used to be called the inert gases until Neil Bartlett proved that you could make compounds out of some of them, so they were renamed "inert" gases.
