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]
Crystals of californium(III) oxide normally have a body-centered cubic symmetry. They convert to a monoclinic form upon heating to about 1400 °C and melt at 1750 °C. [7] Californium(III) chloride (CfCl 3) is an emerald green compound with a hexagonal structure that can be prepared by reacting Cf 2 O 3 with hydrochloric acid at 500 °C. [8]

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.
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]
A minor actinide is an actinide, other than uranium or plutonium, found in spent nuclear fuel.The minor actinides include neptunium (element 93), americium (element 95), curium (element 96), berkelium (element 97), californium (element 98), einsteinium (element 99), and fermium (element 100). [2]
