surface free energy (mJ/m2)

Please ask that how to get atomic "surface free energy" form the periodic table.
I can't get it form the periodic table.

What do you mean exactly by the property "atomic surface free energy"?

Google tells me that
"surface free energy is defined as the work required to increase the area of a substance by 1 sq. cm"

is that what you mean, or is "stomic" surface free energy something different?

I imagine this property is pressure and temperature dependent...

I doubt there's any way to predict it from theory with much accuracy - probably you just have to measure it.
(It's more a physical than a chemical property)

Anyone know of any tabulated values anywhere?
Might be interesting to see how the property varies across the periodic table....

Thank for your reply. :D
Different element has different surface free energy at different surface structure.
For example:Si (111) and (100) have different surface free energy.

Although surface free energy can change with temperature and pressure.
But if we can't change parameter like temperature and pressure.For example: 0 K ,1 atm
We will be able to use surface free energy to understand something about thin film or interface.
Their units are mJ/m2.

I'd like to learn about that. What's the meaning of Silicon (111)?
