How do you find the group number of an element? In chemistry, the valence or valency of an element is the measure of its combining capacity with other atoms when it forms chemical compounds or molecules. This is determined based on the number of electrons that would be added, lost, or shared if it reacts with other atoms. This is because this information determines the kinds of chemical bonds that it can form. Valence of the elements. For example, locate the element oxygen on the table. The elements in each group have the same number of electrons in the outer orbital. For a main group element, a valence electron can exist only in the outermost electron shell; for a transition metal, a valence electron can also be in an inner shell. People also ask, which elements have the same number of valence electrons? Where are the valence electrons in an atom? (2016).
