A permanganate is a chemical compound containing the manganate(VII) ion, MnO 4, the conjugate base of permanganic acid. Because the manganese atom is in the +7 oxidation state, the permanganate(VII) ion is a strong oxidizing agent. The ion is a transition metal oxo complex with tetrahedral geometry. … See more Permanganates can be produced by oxidation of manganese compounds such as manganese chloride or manganese sulfate by strong oxidizing agents, for instance, sodium hypochlorite or lead dioxide See more • Ammonium permanganate, NH4MnO4 • Barium permanganate, Ba(MnO4)2 • Calcium permanganate, Ca(MnO4)2 See more Permanganates(VII) are salts of permanganic acid. They have a deep purple colour, due to a charge transfer transition from oxo ligand p orbitals to empty orbitals derived from manganese(VII) d orbitals.

WebThere are some rules for diagnosing valency. The number of electrons in an unpaired state in the last shell after the electron configuration of an atom is called the valency of that … WebIf we have an ion as a Lewis structure, the ion should have a bracket around the entire structure to show the same thing as the chemical formula, the overall charge of the ion. So my listed examples would have their valance electrons drawn in with a bracket around the ion and the charge in the upper right.
