Californium is a silvery white actinide metal with a melting point of 900 ± 30 °C (1,650 ± 50 °F) and an estimated boiling point of 1,745 K (1,470 °C; 2,680 °F). The pure metal is malleable and is easily cut with a razor blade. Californium metal starts to vaporize above 300 °C (570 °F) when exposed to a vacuum. read more

Californium was first made in 1950 at Berkeley, California, by a team consisting of Stanley Thompson, Kenneth Street Jr., Albert Ghiorso, and Glenn Seaborg. They made it by firing helium nuclei (alpha particles) at curium-242. The process yielded the isotope californium-245 which has a half-life of 44 minutes. read more

Californium is a radioactive metallic chemical element with symbol Cf and Z = 98. The element was first made in 1950 at the University of California Radiation Laboratory in Berkeley, by bombarding Curium with alpha particles (Helium-4 ions). read more
