The relativistic destabilisation of the 6p 3/2 spinor may make francium compounds in oxidation states higher than +1 possible, such as [Fr V F 6] −; but this has not been experimentally confirmed. [5] Francium perchlorate is produced by the reaction of francium chloride and sodium perchlorate.

See Weight for detail of mass/weight distinction and conversion. Avoirdupois is a system of mass based on a pound of 16 ounces, while Troy weight is the system of mass where 12 troy ounces equals one troy pound. The symbol g 0 is used to denote standard gravity in order to avoid confusion with the (upright) g symbol for gram.
