Cohesive, binding, atomization, ionization energy

    Hi all,

    I would like to know what the difference between ionization, binding, atomization and cohesive energies is?

    Ionization energy - the energy required to ionize an atom or molecule, i.e. remove an electron from it.
    Binding energy - the energy gained from chemical binding, usually measured against the element in its 'pure' form, e.g. an O2 molecule for oxygen.
    Atomization energy - the energy required to get from that 'pure' form above, to free, neutral single atoms.
    Cohesive energy - the binding energy for the atoms of a crystal, measured against the state of neutral free atoms.
