Adding Electrons to hydrogen?

  1. Apr 25, 2013 #1
    If you stuck 1 electron into the inner shell of a hydrogen atom, would the properties change?

    Thanks all,

    The neutral hydrogen atom has one electron in the ground state.
    What do you mean by "inner shell"? There is no level lower than the ground state.
    If you put another electron on the level where there is one already, you have a negative ion.
