<P> The number of valence electrons of an element can be determined by the periodic table group ( vertical column ) in which the element is categorized . With the exception of groups 3 -- 12 ( the transition metals ) , the units digit of the group number identifies how many valence electrons are associated with a neutral atom of an element listed under that particular column . </P>
