[Pw_forum] The difference between binding energy and cohesive energy.

[Hongsheng Zhao]

Hi all,

Does the binding energy and cohesive energy mean the same thing or not?

 From here: http://www.physicsforums.com/showthread.php?t=300117

I find the following explains:

Binding energy - the energy gained from chemical binding, usually 
measured against the element in its 'pure' form, e.g. an O2 molecule for 
oxygen.

Cohesive energy - the binding energy for the atoms of a crystal, 
measured against the state of neutral free atoms.

But, I also read some references which regards them as same thing.

Any hints?

Regards.
