WebDec 15, 2024 · 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. WebConsider a Ionic Compound. NaCl , (Na+) and (Cl-) ions are present in this. Na have 1 +ve charge. Cl have 1 - ve charge. Total charge = (+1)+ (-1) =0 ie, neutral. The charge on the anion is balanced by the charges on and numbers of the cation. Of course, in solution, these species might ionize to give solvated ions.
