The number of valence electrons in an atom can often be quickly determined by referencing A. the atomic number of the element. B. the period number on the periodic table. C. the group number on the periodic table. D. the atomic mass of the element.
Weegy: The number of valence electrons in an atom can often be quickly determined by referencing C. [ the group number on the periodic table. 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 number within the unit's place identifies how many valence electrons may be associated with a neutral atom of an element listed under that particular column. ] User: Which of the following men did not help to advance the understanding of the atom?
