= Ideal Fermi gas bulk modulus
{title2=$B=\frac23nE_F$}

For a nonrelativistic three-dimensional ideal electron gas at zero temperature, the pressure is $p=2nE_F/5$ and the electronic <bulk modulus> is $B=2nE_F/3$. This is the electronic model contribution, not automatically the total bulk modulus of a real crystal.
