The molecular formula is CoO Cation is Co^2+^Anion is O^2-^or in other wordscobalt(II) oxide = CoO = Co2+ + O2-
A Hydrogen ion is written as H+.
Assuming that cobaltic oxide is the only cobalt-containing constituent of the rock, the mass of cobaltic oxide in the rock is 56.7(0.567) or 32.149 mg. The formula of cobaltic oxide is Co2O3 and its gram formula mass is 165.86. The formula shows that each formula unit contains 2 atoms of cobalt. The amount of 32.149 mg corresponds to (32.149 X 10-3)/165.86 or 1.938 X 10-4 formul units of cobaltic oxide. The number of atoms in this mass is therefore Avogadro's Number X 2 X 1.9438 X 10-4 or 2.34 X 1020 atoms of cobalt, to the justified number of significant digits.
Correctly written it is 'CH3COO^- ' it is a conjugate base. It is named as Ethanoate ion or Acetate ion.
Lead is chemically written as Pb2+, an double positive ion (cation)
Cobaltous ion has a +2 oxidation state. Cobaltic ion has a +3 oxidation state Cobaltous chloride: CoCl2 Cobaltic chloride: CoCl3
