PCl 4- is a negative ion (an anion) so you have to add an extra valence electron. In the PCl 4- Lewis structure Phosphorus (P) is the least electronegative so it goes in the center. In the Lewis structure for PCl 4- there are a total of 34 valence electrons. Four pairs will be used in the chemical bonds between the P and F.

Valence electrons. Valence electrons are the electrons in the outermost shell, or energy level, of an atom. For example, oxygen has six valence electrons, two in the 2s subshell and four in the 2p subshell. We can write the configuration of oxygen's valence electrons as 2s²2p⁴. Created by Sal Khan. Exception 1: Species with Odd Numbers of Electrons. The first exception to the Octet Rule is when there are an odd number of valence electrons. An example of this would be Nitrogen (II) Oxide also called nitric oxide ( NO NO. Nitrogen has 5 valence electrons while Oxygen has 6. The total would be 11 valence electrons to be used.Also, only 24 valence electrons of SOF2 molecule are used in the above structure. But there are total 26 valence electrons in SOF2 molecule (as calculated in step #1). So the number of electrons left to be kept on the central atom = 26 – 24 = 2. So let’s keep these 2 electrons (i.e 1 electron pairs) on the central atom. Valence electrons are the electrons present in the outermost shell of an atom. You can easily determine the number of valence electrons an atom can have by looking at its Group in the periodic table. For example, atoms in Groups 1 and 2 have 1 and 2 valence electrons, respectively. Atoms in Groups 13 and 18 have 3 and 8 valence electrons ... Chlorine has seven valence electrons. Chlorine has atomic number 17. The atomic number is the number of protons present in the nucleus of an atom.All the atoms of an element have same atomic number. In every stable atom the number of electrons is equal to the number of protons. Stable means that atom has not formed a ion yet.
