Quick Summary

Monovalence refers to an element's capacity to combine with one other atom. This property is determined by the number of valence electrons an atom possesses, which are the electrons in its outermost shell. These electrons are crucial for forming chemical bonds. Elements with a valence of one, like hydrogen, typically form a single bond. Historically, valence was measured by the number of hydrogen atoms an element could combine with or replace. The concept has evolved with the understanding of electron behavior in atomic structures and chemical interactions.123

Conductivity of metals
…to become conduction electrons, while monovalent atoms, such as lithium or gold, donate one. As will be recalled, the number of conduction electrons alone does not determine conductivity; it depends on electron mobility as well. Silver, with only one conduction electron per atom, is a better conductor than aluminum with…
