Introduction to californium (Cf)
Californium symbolized by Cf is radioactive material. It is an artificially created radioactive ingredient. The atomic number of californium Cf is 98.
Californium is one of the transuranium parts within the actinide collection of the periodic desk. It exists as solid at 20°C.
The isotope of californium with atomic mass variety of 245 was first produced in 1950 on the College of California laboratories in Berkeley by the American chemists Stanley G. Thompson, Kenneth Road, Jr., Albert Ghiorso, and Glenn T. Seaborg. Therefore, it is known as californium.
Properties of californium (Cf)
Melting point 900°C, 1652°F, 1173 K'
Boiling point Unknown
Density 15.1 (g cm−3)
Key isotopes 249 Cf, 252 Cf
Electron configuration [Rn] 5f107s2
Production of californium
The scientists created californium-245 by bombarding curium-242 with alpha particles in a 152-cm (60-in) cyclotron.
Californium did not exist in weighable quantities until ten years after its discovery. It is prepared, in milligram quantities solely, by the neutron bombardment of plutonium-239.
Californium-245 quickly decays, with the emission of alpha particles, having a half-life of 44 min. Isotopes, with mass numbers from 240 to 255, have been subsequently ready.
Californium-249 is the results of the beta decay of berkelium-249. The heavier californium isotopes are produced by neutron bombardment of berkelium-249, which will increase the variety of protons within the nucleus.
Californium-252, with a half-life of two.6 years, has an unusually excessive charge of spontaneous fission, with an ample emission of neutrons.
Uses of californium (Cf)
Californium is a sturdy neutron emitter. It is utilized in transportable steel detectors, for figuring out gold and silver ores, to determine water and oil layers in oil wells and to detect steel fatigue and stress in aeroplanes.
Californium Cf has sensible utility as a high-intensity neutron supply in digital techniques and medical analysis.
Due to its high toxicity is has no biological applications yet.
Probably the most steady isotope of californium, with a half-life of about 900 years, has an atomic mass variety of 251.
