Few compounds of californium have been made and studied. [1] The only californium ion that is stable in aqueous solutions is the californium(III) cation. [2] The other two oxidation states are IV (strong oxidizing agents) and II (strong reducing agents). [3]
Californium is a silvery-white actinide metal [12] with a melting point of 900 ± 30 °C (1,650 ± 50 °F) and an estimated boiling point of 1,743 K (1,470 °C; 2,680 °F). [13] The pure metal is malleable and is easily cut with a knife. Californium metal starts to vaporize above 300 °C (570 °F) when exposed to a vacuum. [14]

Californium oxychloride (Cf OCl) is a radioactive salt first discovered in measurable quantities in 1960. It is composed of a single californium cation and oxychloride consisting of one chloride and one oxide anion.
A dication is any cation, of general formula X 2+, formed by the removal of two electrons from a neutral species. Diatomic dications corresponding to stable neutral species (e.g. H 2+ 2 formed by removal of two electrons from H 2) often decay quickly into two singly charged particles (H +), due to the loss of electrons in bonding molecular ...
