WebCalifornium is a synthetic radioactive element found on the bottom row of the periodic table, along with other actinides. It was first discovered in 1950 at the University of California Radiation Laboratory in Berkeley by bombarding curium with alpha particles (helium nuclei). WebCalifornium polyborate is a covalent compound with formula Cf[B 6 O 8 (OH) 5].In this compound the californium is in a +3 oxidation state.. Californium polyborate is unusual in that californium is covalently bound to the borate. Californium was expected to resemble lanthanide elements in being highly ionic. The polyborate anion is polarisable and flexible. …
