You rub two insulators against each other and attain a charge imbalance. Is there a rule as to which of the materials will end up with a negative charge and vice versa? Does it depend on which one has more or less lose valence electrons?

there is empirical series of materials sorted from which one is most likely to lose vs gain electrons, but what exactly happens is one of unsolved problems in physics
