helium doesn't form any compound
Helium does not form any compound.
Helium is chemically inert. It doesn't form any compound and has no charge.
Helium is inert and doesn't react with any other elements.
NO!!!! He (Helium) is monatomic gas, that is it exists as single atoms, and does NOT combine with any other substance to form a compound. 'He' is the most inert element of all. It alsao has the lowest condensing point 4K4 (-269 oC) and freezing point at 2K (-271oC).
He, helium, is an element. It is a noble gas and it does not form any chemical compounds.
Sun is a star not a chemical compound; any chemical equation for Sun. Sun contain hydrogen, helium and other minor elements.
Salt and water do not form a compound of any kind - neither decimal nor chemical.
Helium is a noble gas and typically does not form compounds with other elements due to its stable electron configuration. However, in extremely rare cases, helium can form compounds with highly electronegative elements under specific conditions, such as with fluorine to form helium difluoride (HeF2) or with oxygen to form helium oxide (HeO2).
It doesn't. Helium is chemically inert or doesn't have any chemical property.
Helium's chemical property is its low reactivity.
It is a compound, not an element. N4Se4 is tetranitrogen tetraselenide
