Elements are only what you find on the Periodic Table like oxygen, hydrogen, sodium, etc. Compounds would be multiple elements like CO2 or H2O
And a mixture is things like cake mix or an egg. Which means that an egg is a mixture.
compound
chalk is a compound
Hydrogen flouride is a compound.
C2H6 (ethane) is neither a mixture nor an element. It is a molecular compound since it contains different atoms but is not mixed with other compounds.
Air is a mixture, made mostly of the elements nitrogen and oxygen. It also has some other gases, such as argon (element), carbon dioxide (compound), and water (compound).
It is a heterogeneous mixture.

First of all you have mispelled it as 'hellium' . It is 'HELIUM'. It is an element. It atomic No. is '2' , so therefore it is found in position number '2' in the Periodic Table, as 'He'. It is neither a compound nor a mixture. The chemical symbol for helium is 'He '. It's Atomic Mass is '4' It is compsed of 2 protons, 2 neutrons and two electrons. It is the MOST Noble(Inert) of all the elements. It does NOT react with anything. Therefore it exists 'monatomically' (single atoms). Its condensing point is 7 K ( - 266 oC) (Becomes a liquid) Its freezing point is 4 K . ( - 269 oC) (becomes a solid). The name 'helium' is from Classical Greece, and means 'from the Sun'(Helios), because two hydrogen atoms fuse together in the Sun , they form 'Helium'.
