Helium is an element which makes it a pure substance.
Neither. Helium is not a mixture at all, it is a pure substance.
No. It will be a homogeneous mixture of gases.
No, helium is not an example of a heterogeneous substance. Helium is a pure element, which means it is uniform in composition throughout and does not contain different types of molecules or substances mixed together.
No, helium is a pure substance and an element to be more specific. It has a constant composition making it a pure substance and it is homoatomic (has only one type of atom) which makes it an element.
The oxygen and helium in a scuba tank are considered a homogeneous mixture, not a compound or a heterogeneous mixture. In this case, the gases are mixed together uniformly, and their individual properties remain unchanged. A compound consists of two or more elements chemically bonded together, while a heterogeneous mixture would have distinct, separate components.

The sun is a star made primarily of hydrogen and helium gases undergoing nuclear fusion, making it a homogeneous mixture of elements.
