A:
Helium is an element like Oxygen, Hydrogen, Iron, etc. Elements are composed of a specific number of electrons and protons. Compounds and molecules are created by sharing, losing, or gaining electrons. Each element has a specific number of electrons which makes it most stable. For Helium, Neon, Xeon, and other noble gases; they start out with this stable number of electrons. Because these elements do not need more or less electrons, they typicall do not bind with other elements to form compounds.

However, it is possible to force these noble gases to bind to other compounds if we use high energies. For example, Xenon TetraFloride is often used as an insulator for high voltage equipment because the Xenon refuses to accept electrons and thus preventing electricity from traveling. Another interesting example is that a helium atom can be contained in a molecule of Carbon-60 (also know as a Bucky Ball).

However, these are very rare instances. In general, Helium and other noble gases do not form compounds.
