Helium is an element that has physical properties. So far it has eluded efforts to make it react with anything else. It could thus be argued it does not have chemical properties other than it is very inert.
No. This is because it is demonstrating the fact that it is less dense than the air. Density is a physical property. Therefore the helium balloon rising to the ceiling is not a chemical property, and instead a physical property.
Helium's chemical property is its low reactivity.
chemical property
Yes, liquid helium boiling is a physical property. Boiling point is a physical property that describes the temperature at which a substance changes from a liquid to a gas. In the case of helium, its boiling point is very low at -268.9 degrees Celsius.

No that is a physical property.

Helium is an element a pure substance it is a chemical. It has properties eg it is a gas, it is colourless, it is odourless
It doesn't. Helium is chemically inert or doesn't have any chemical property.
Helium's chemical property is its low reactivity.

"Unreactive" is a chemical property because it describes an element or compound's tendency to undergo chemical reactions with other substances. It refers to the ability or inability of a substance to react in a chemical change under specific conditions.

i am pretty sure it is a physical property! :)
