Q
● These are the electrons located at the outermost
(highest) principal energy level of a representative or
noble gas element.
● Assigning valence electrons is only applicable to
representative elements, that is, groups IA to VIIIA
(transition elements in the d sublevels are NOT
included)
● It is, therefore, common to see valence electrons in
the s or p sublevels.
