The Ratio of Valence Electrons to Atoms in Metals and Intermetallic Compounds

It is shown that the numbers of valence electrons assigned to the $\gamma$-alloys, $\beta$-manganese and alloys with similar structure, and $\alpha$-manganese by a new system of metallic valences agree closely with the electron numbers calculated for complete filling of important Brillouin polyhedra for these structures.
