A free electron system consists of (N) atoms, having electrons of mass (m), in a 3-D lattice of dimensions (L3).
where E is the system's ground state energy, N is the number of electrons in the gas system.
The bulk modulus (B) and compressibility (K) are derived through the relation:
B = 1/K =
Show that this gives approximately 9 GPa for sodium and 3 GPa for potassium.
How does this compare with experimental results?
e-mail me (email@example.com) two web-site URLs that describe the free electron model and the expected behavior of metals regarding heat and electricity.
