Helium is a noble gas so it doesn't give away any electrons, it has two electrons (not one). The valence of Helium is 0.Source(s): Biology Major

Helium is in group 18 in the periodic table. This group contains the noble gases. None of the elements in this group react with other elements. They have full outer shells. In the case of Helium, it can only hold 2 electrons in its outer shell. Helium already has two. Valence electrons are the outer shell electrons, therefore, it has two valance electrons.
