does it have any compound?
Yes, its molecular compounds are HeNe, HgHe, and WHe.
Helium
The molecular compounds HeNe, HgHe, and WHe, and the molecular ions , , , and have been created this way. HeH is also stable in its ground state, but is extremely reactive—it is the strongest Brønsted acid known, and therefore can exist only in isolation, as it will protonate any molecule or counteranion it contacts. 
where does the world's helium come from Most helium on Earth is a result of radioactive decay and is found in large amounts in minerals of uranium and thorium, including uraninite. how is it extracted? UNANSWERABLE does it have any uses? Yes, commercial, recreational, scientific as well as medical use. what are its commercial use? One of its commercial use is that its mixtures such as trimix, heliox and heliair are used for deep diving to reduce the effects of narcosis, which worsen with increasing depth. what are the characteristics of it? In the perspective of quantum mechanics, helium is the second simplest atom to model, following the hydrogen atom. how was it discovered? he first evidence of helium was observed on August 18, 1868, as a bright yellow line with a wavelength of 587.49 nanometers in the spectrum of the chromosphere of the Sun.

Helium [SEP] Compounds
HeH is also stable in its ground state, but is extremely reactive—it is the strongest Brønsted acid known, and therefore can exist only in isolation, as it will protonate any molecule or counteranion it contacts. This technique has also produced the neutral molecule He, which has a large number of band systems, and HgHe, which is apparently held together only by polarization forces. Van der Waals compounds of helium can also be formed with cryogenic helium gas and atoms of some other substance, such as LiHe and He. Theoretically, other true compounds may be possible, such as helium fluorohydride (HHeF) which would be analogous to HArF, discovered in 2000.
