WebIt is monatomic. Helium is a member of the noble gases which means it has a filled outer shell of electrons. With a full outer shell, it doesn’t take part in most chemical reactions without a lot of forcing. It certainly won’t react in the way required to form He2. This is true of the other noble gases (neon, argon, etc.).
