helium has no physical or chemical change helium has no physical or chemical change
Helium does not undergo chemical changes under normal conditions because it is a noble gas with a full outer electron shell, making it very stable. Helium can only react under extreme conditions, such as high pressure and temperature, to form compounds with highly electronegative elements.
The chemical formula for helium is He. It is a noble gas with an atomic number of 2.
