      In aqueous solution, transition metal cations are usually symbolized as Mn+(aq), where M is the atomic symbol of the metal ion and n is the charge on the ion. For example, Fe3+ in aqueous solution is written as Fe3+(aq). The (aq) symbol indicates that the metal ion is aquated. = Fe = O = H [Fe(OH2)6]3+

      Non-metals which tend to have their atoms gaining electrons during chemical change are roughly found in Group16-17 with some elements in the lower parts of Groups 15. Metalloids which tend to have their atoms sometimes losing and sometimes gaining electrons during chemical change are generally found in …

      Charges of most polyatomic ions with oxygen: To figure out the charge instead of memorizing it, first look on the perioidic table and find symbol of the non-oxygen atom in the polyatomic ion. Take the last digit of its column number and subtract (2) (number of oxygen). This will be the charge on the polyatomic ion. Remember the “Elbow”
