Helium is a noble gas, a nonreactive chemical element.
Helium is an inert element where it has two electrons in the first energy level. It is also known as the lightest noble gas.
Helium is an extremely unreactive gas; only a small number of compounds are known, stable only at extremely high pressures or low temperatures.
It is a chemical property.

Its a physical property as it is not involved with chemical reactions.
Noble gases are very unreactive.

i am pretty sure it is a physical property! :)
Your SENSE of smell is physical, but smells are created by chemical interactions.
