There are no known compounds of helium. Helium is a noble gas , it has a full valence shell with 2 electrons, (1s2).
Helium does not exist in atmosphere as it is a very light gas.
Helium does not combine with other elements and pure helium will exist by itself as elemental helium.
nothing helium will not bond with anything and there for can not create a compound But there may be a few derivatives of a metastable F HeO- anion, in which helium is covalently bonded to oxygen.
Covalent.Every compound can exist as a solid, liquid, or gas, given the right temperature and pressure. This is also true of every element, with the single exception of helium, which has no solid phase, no matter how cold it is. Helium is unique.
No. Helium is not an compound, it is a element.
Helium is not a compound, it is an element.
Helium is not a compound, it is an element.
Helium is an element and not a compound or mixture.
A compound must have at least two atoms of different elements.
No it is not, helium is an element. A compound is a combination of two or more elements.
Helium (He) is a chemical element, not a compound; the chemical symbol is He.
helium doesn't form any compound
