Helium is a pure substance because it is composed of only one type of atom (helium atoms). It is a noble gas with a uniform composition throughout, making it a homogeneous substance.
Heterogeneous refers to something that is composed of different or diverse elements. For example, a heterogeneous mixture is one in which the components are not uniform throughout. Heterogeneous can also describe a group of individuals with varied characteristics.
