When drawing the structure of an ion, be sure to add/subtract electrons to account for the charge. Step 2: Connect the atoms to each other with single bonds to form a “skeleton structure.”. Here, V (valence electron of central atom) = 5 M ( monovalent atom) = Cl = 3 As it is a neutral compound thus C and A will be 0. Thus , H= ½ [5+3] = ½ * 8 = 4 = Sp3. These two concepts clearly explain the Sp3 hybridization of PCl3. … AboutTranscript. When forming ions, elements typically gain or lose the minimum number of electrons necessary to achieve a full octet. For example, fluorine has seven valence electrons, so it is most likely to gain one electron to form an ion with a 1- charge. We can use this method to predict the charges of ions in ionic compounds.
