...There are also complex carbides such as Cr 23 C 6 and Mn 23 C 6 . (3) Electron compound. An intermediate phase recognized by W. Hume-Rothery and others around 1926, it is a compound that appears when the ratio of the sum of the valence electrons of the alloy (counted as 0 for Fe, Co, and Ni, 1 for Cu, Ag, and Au, 2 for Mg, Zn, and Be, 3 for Al, and 4 for Sn and Si) to the number of atoms is a certain ratio such as 3/2, 21/13, or 7/4 (Hume-Rothery rule). ... *Some of the terminology that refers to "electron compound" is listed below.
