When I calculate the Bulk modulus for a metall with the free electron model
I get a value that is twice the experimental value.
I find this strange.
With the free electron model i don't get the contribution from the ion cores and the bound electrons, right?
Do these have a negavite contribution to the bulk modulus.
If so, why?
The magnetic suceptibility has a positive contribution from the free electron paramagnetism and a negative from the diamagnetism. Where the diamagnetism comes from the ion cores and the bound electrons. This i can understand...but how can the bulk modulus have a negative contribution??
