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]
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-252 production diagram. Californium-252 (Cf-252, 252 Cf) undergoes spontaneous fission with a branching ratio of 3.09% and is used in small neutron sources. Fission neutrons have an energy range of 0 to 13 MeV with a mean value of 2.3 MeV and a most probable value of 1 MeV. [11]
Californium(III) oxide forms a yellow-green solid with a melting point of 1750 °C and exists in three modifications. [2] The body-centered cubic modification forms a crystal lattice with a = 1083.9 ± 0.4 pm. The transition temperature between body-centered cubic and monoclinic structures is about 1400 °C. [3] [4] It is insoluble in water. [5]
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.
Californium(III) nitrate is an inorganic compound of californium and iodine with the formula Cf(NO 3) 3. [1] It can be used as a precursor to other californium ...
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 ...
