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 … WebSulfur has 6 Valence electrons, 2 in the first shell, 8 in the second shell, and 6 in the outermost layer (third layer). They can determine the number of kernel electrons and the number of valence electrons due to the bonds they form, for example Sulfur is more likely to form ions with the Alkaline earth metals and form different covalent bonds.
