This element was named after California, the US state where it was first made. Californium is a raw material used for making very heavy elements, such as oganesson. It is one of the world’s most expensive substances: a gram of californium costs US$27 million. This is because it is difficult to produce this highly radioactive element, making it rare. • ATOMIC MASS (251) • STATE Solid • DISCOVERY 1950 (Stanley Thompson, Kenneth Street Jr, Albert Ghiorso, and Glenn T Seaborg) • Californium is named after the US state of California. This soft, silvery metal does not exist in nature and is made by smashing berkelium atoms with neutrons in a particle accelerator (a machine in which atoms are smashed together). This radioactive element is used in the treatment of cancer. • Pellets of radioactive californium: • This isotope, or form, of Californium produces a lot of neutrons. • Water detector: This machine uses californium to find water underground. • #allinfobits #actinides #californium #waterdetector #californium252 #radioactive #periodictable #fblock
