Because it has 2 electrons which fill up its electron shell, making it unreactive and stable.

What compounds contain helium?
There are none. Helium does not form any compounds.
Does helium form compounds?
Answer:Helium is an inert gas and does not easily form any compounds, in fact there are no known compounds. (It's valence shell is full to capacity, 1s2.) In an electrical discharge it can form metastable 'compounds' called excimers (short for excited dimers) with tungsten, iodine, sulfur, fluorine, phosphorus and sulfur. These are short lived entities, lifetime typically measured in nanoseconds, that are formed by excited helium atoms.There is some thought that helium may react like argon and form helium fluorohydride (HHeF) similar to the argon compound HArF.The curious investigator could use the link below to surf to the Wikipedia post on the compounds of helium. It's only two paragraphs long and easy to read. Why not pull out the stops and go for it?
Helium and neon cant form compounds with fluorine why?
The first Ionization energy of fluorine is less than that of the helium and neon.
What is a element that will not form a compound?
Group 0 Elements ( Helium, Neon, Argon...) do not form compounds because they have a complete Octet and are thus unreactive and exist as mono atomic elements
Can helium and chlorine combine to form an ionic compound?
No, it rarely bonds with other elements, and if it does the only one it would bond with would be Fluorine, which they have done before, and if and when it bonds with fluorine and/or oxygen, it would form a covalent bond. If you were to to take either of the two elements and try to perform an chemical reaction, when you find the electro negativity (ΔEn, which is equal to En2-En1) you will notice that it will fall below 0.5 or greater than 1.7 , which will be a covalent bond (an ionic bond will be between 0.5 and 1.7).
What are the compounds for helium?
Helium does not form compounds.
What are the compounds formed by helium?
Helium does not form any compounds.
List the helium compounds?
helium doesnot form any compounds
What compounds does helium contain?
helium doesnot form any compounds
What are common compounds for helium?
There are no common compounds of helium and probably are no compounds of helium at all, because helium is the least reactive of all elements.
What is a compound with helium in it?
helium doesn't form compounds
Explain why helium does not react with other element to form a compounds?
why helium does not react with other elements to form compounds
What are three examples of compounds that are formed by helium?
Helium doesnot form any compounds.
Why does helium form compuonds?
Helium is chemically inert and does not form any compounds.
What type of molecules is helium likely to form?
Helium does not form any compounds.
What are some uses of compounds that contain helium?
Helium is chemically inert and does not form any compounds
Why doesn't helium form compounds?
Helium does not form compounds because of the electrons doesn't attract to nutrons Helium does not form compounds because the outer (only) shell of electrons is full. This is the valence shell, and in order for elements to form compounds, the valence shell must have available slots. Helium does not have any available slots in the valence shell, hence its inability to form compounds.
