The belоw MO diаgrаm is fоr H2 . A hydrоgen аtom contains one valence electron, therefore the 1S atomic orbital contains a single electron. This is true for each hydrogen atom. The middle of the MO diagram shows the molecular orbitals that have been filled with the valence electrons from the original atoms. Elements in the first period will have MO diagrams that look something like this: Consider the above diagram for H2. If we add an electron to this system to form H2-, in which orbital would you place the new electron?
