Helium is a pure element. But gases can be mixed with other gases. The helium in tanks used for inflating balloons is doubtless a mixture.

Helium is a single chemical substance but an isotopic mixture, 1.37x10^(-6)% helium-3. He-3 is wicked fun in helium dilution refrigerators. He-3's industrial source is tritium decay.

Helium is a pure substance since it is a single element (you can find it on the Periodic Table of Elements - He)

Pure substance. An element. Look at the first row, all the way to the right.

heterogeneous means "different phase" and homogeneous means "same phase". if the oxygen and helium are both gases inside the tank, then it will be a homogeneous mixture.
