No -
it is an element all in itself.
An example of a gas mixture is carbon dioxide,
made of a mixture of oxygen and carbon.
So helium is just helium; nothing mixed in with it.
Helium is gaseous but it is not a mixture - it is a chemical element.
A mixture of oxygen and helium is used in diving.
Helium, hydrogen, and air are gases.
Ammonia is a compound, not a mixture.
Neither. Helium is not a mixture at all, it is a pure substance.

Helium is a gaseous chemical element.
When hydrogen and helium are mixed, they will not react chemically because they are both inert gases. Instead, they will form a gaseous mixture with the properties of both gases, maintaining their individual characteristics.
in gaseous state.
