Cohesive, binding, atomization, ionization energy

Hi all,

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

Regards,
Sara

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.
