Determining the number of valence electrons
WebAug 4, 2024 · The best approach to identify the number of valence electrons is to use the abbreviated notation for electron configuration. In this notation, the inner-shell electrons … WebThe term valence refers to the ability of an element to form bonds with other atoms. An element’s valence was historically determined by how many hydrogen atoms it could bond to (which is determined by how many valence electrons it has available for bonding): for example, carbon can form CH 4 so it has a valence of 4, and 4 valence electrons. On …
