For the first time californium is obtained with the nuclear reaction:
Cm-242 + He--------------Cf-245 + n
The important isotope Cf-252 is obtained in nuclear reactors after a long time irradiation of plutonium with neutrons.
Californium was discovered in 1950.
Californium can react with the majority of non metals.
Californium react with oxygen, nitrogen, sulfur, hydrogen, halogens, etc.
Yes, many laboratories in the world make studies on californium and on the applications of Cf.
When californium emits an alpha particle, it creates curium.
Glenn T. Seaborg did not make californium himself; it was discovered by a research team at the University of California in 1950. The element was first synthesized by bombarding curium-242 with alpha particles to produce californium-245. Seaborg played a key role in the discovery and identification of californium, as well as in its naming after the state of California.
Not californium, but neutrons emitted by californium.
Protons, neutrons and electrons
All the isotopes of californium are radioactive, artificial and unstable.
Californium has 98 protons.
Californium is radioactive and a strong neutrons emitter; californium can be lethal.
Californium is a metal.
