About the energy necessary to pull out the closest electron of a atom

  1. Feb 14, 2014 #1
    Dear friends,
    I was wondering what would be the necessary amout of energy to pull out the closest electron of an iron metal. I read that the energy required for the most distant electrons of the iron metal is about 9 thousand KJ/mol.

    Thanks my sages@

    For bulk iron?
    That would be the work-function ... defining "closest" as the electrons with the least binding energy.

    Exactly the same energies are involved in Auger effect.
