Did you know?
Helium is the smallest and the lightest noble gas and one of the most unreactive elements, so it was commonly considered that helium compounds cannot exist at all, or at least under normal conditions. Helium's first ionization energy of 24.57 eV is the highest of any element. Helium has a complete shell of electrons, and in this form the atom does not readily accept any extra electrons nor join with anything to make covalent compounds. The electron affinity is 0.080 eV, which is ver… WebHelium is a gas that is only found where a coincidence of unlikely situations occur. Although it is continually being produced by radioactive mineral decay in Earth's crust, its rate of natural production and accumulation is so slow that it should be considered a nonrenewable resource.
