In the Quantum Theory of the elements, the valence level is defined as the highest principle quantum number of the electron configuration of that element. Two oxygen atoms are bound covalently to get rid of valency and form O2 gas. True or false? To see how many of these electrons are valence electrons, write the electron configuration of a neutral zinc atom. Valence electrons are the outermost electrons which, therefore, are located on the highest energy levels. Helium only has 2 electrons total and they are all on the same shell. As a result, neutral helium will only have 2 electrons surrounding its nucleus. But for this, you have to know what these two terms Therefore, hydrogen has only one electron which is present in the "1s" orbital.
