Abstract
This work proposes new assumptions in place of some basic erroneous assumptions of free electron theory to determine n, the number of highest energy electrons, and Fermi energies are recalculated accordingly. The bulk modulusof metals are calculated using both the number of highest energy electrons in atoms proposed in this work and original free electron theory assumptions. When compared to measured values there is a much better agreement with valuesdetermined by this work than those using the original free electron theory assumptions. There is fairly good agreement between Fermi energies calculated by the standard theoretical equation and estimates using an approximation proposed by this work.
