The phosphorus atom belongs to group 15 of the periodic table and thus contributes 5 valence electrons. On the other hand, every chlorine atom contributes 7 valence electrons, because this element belongs to group 17. Thus, we compute the total valence electrons as follows:

Valence is typically the number of electrons needed to fill the outermost shell of an atom. Because exceptions exist, the more general definition of valence is the number of electrons with which a given atom generally bonds or number of bonds an atom forms. (Think iron, which may have a valence of 2 or a valence of 3.)The dot diagram shows that sulfur has 12 electrons in its valence shell. Here the sulfur atom has six electron pairs in its valence shell. An atom like phosphorus or sulfur which has more than an octet is said to have expanded its valence shell. This can only occur when the valence shell has enough orbitals to accommodate the extra electrons.Here is a table of element valences. Remember that an element's electron cloud will become more stable by filling, emptying, or half-filling the shell. Also, shells don't stack neatly one on top of another, so don't always assume an element's valence is determined by the number of electrons in its outer shell.A step-by-step explanation of how to draw the PCl4- Lewis Dot Structure.For the PCl4- structure use the periodic table to find the total number of valence el...3.1: Valence Electrons is shared under a CC BY-NC license and was authored, remixed, and/or curated by LibreTexts.
