Californium is an artificial chemical element.
Californium is an artificial chemical element !
Californium is a member of the actinides group.
Californium is a pure element.
Californium is a solid metal, radioactive, unstable.
Californium is a man made element; usually found in nuclear physics/radiochemistry laboratories.
Californium was not used in nuclear weapons. While not used, californium is produced in fusion (hydrogen) bomb explosions and is found in their fallout.
Californium does not occur naturally. It is produced as a result of nuclear explosions and nuclear experiments.
The first isotope of californium was discovered in 1950 at Berkeley Radiation Laboratories, California, USA.
Californium is radioactive and all the applications of it involve its radioactivity rather than its chemitry, so you might find it in neutron moisture guages for example.
Californium is an artificial element; the natural element exist only in infinitesimal traces in uranium ores.
Californium was obtained by Stanley G. Thompson, Kenneth Street, Albert Ghiorso and Glenn Seaborg in 1950 at Berkeley Laboratories.
