Hume-Rothery rules

Physics

A set of empirical rules put forward in 1926 by the British metallurgist William Hume-Rothery (1899–1968) to describe how one metal dissolves in another metal. He found that one metallic element will not dissolve in another if the difference in their atomic radii is greater than 15% or if the electronegativities of the two elements differ substantially. Also, A metal with a lower valency is more likely to dissolve in one with a higher valency, than vice versa. These rules were subsequently justified by the quantum theory of electrons in solids.

Chemistry

A set of empirical rules put forward in 1926 by William Hume-Rothery to describe when one metal can dissolve in another metal to form a solid solution. One metallic element will not dissolve in another metallic element if the difference between their atomic radii is more than about 15% or if the electronegativities of the elements are substantially different. A metal with a lower valence is more likely to dissolve in a metal of higher valence than vice versa. These rules are very similar to Goldschmidt’s rules for minerals, which were proposed in the same year. See also isomorphous substitution.
