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 dichloride is a binary inorganic compound of californium metal and chlorine with the chemical formula CfCl 2. [1] Synthesis. CfCl 2 can be prepared by ...

Californium (98 Cf) is an artificial element, and thus a standard atomic weight cannot be given. Like all artificial elements, it has no stable isotopes. The first isotope to be synthesized was 245 Cf in 1950. There are 20 known radioisotopes ranging from 237 Cf to 256 Cf and one nuclear isomer, 249m Cf.
One of the elements is Californium, which he and several others made. Thompson was also a leader of the research teams that discovered the next three transuranium elements: einsteinium, fermium and mendelevium (atomic numbers 99, 100 and 101). [1] He received Guggenheim Fellowships (Natural Sciences - Chemistry) in 1954 and 1965. [2]
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 is a chemical element with symbol Cf and atomic number 98. Californium may also refer to: Californium, a 2016 video game ...
