Valence electrons are the electrons in the outer energy level of an atom that can participate in interactions with other atoms. The type of orbital (s, p, d, or f) that the valence electrons reside in is a function of the elements' position in the periodic table. An explanation and practice for finding the number of valence electrons for elements on the periodic table. The rule is as follows: If an element is not a transition metal, then valence electrons increase in number as you count groups left to right, along a period. pt. In the periodic table, elements with similar chemical properties are in the same group. Locate the transition metal on the periodic table and make note of the group number. Periods correspond to the number of electron shells possessed by atoms of the elements in that row. You may already know that an electron is a negatively charged particle of an atom. Each electron shell can hold a fixed, maximum number of electrons: the K shell holds a maximum of two electrons, the L shell holds eight electrons, the M shell holds eighteen electrons and the N shell holds a maximum of thirty-two electrons. Count the valence electrons on the metal; Figure \(\PageIndex{2}\): Counting electrons on the ligands and the metal.
