What is the history of California discovered and named by that name

Cf radioactive chemical element, trivalent. [1] plant chemical element in the periodic table symbol (palm - Cf) its atomic number 98 was discovered by

extrusion element curium alpha particles and has a few uses


Properties
It 252cf have a half-life of 2.6 years with a high radioactivity. Where is the source of neutrons (1 micro gram of it radiates about 170 million neutrons per minute.) Does not have any role in Baolga life and little studied compounds such as (Cf2O3) (CfCl3) (CfOCl)


History
It was synthesized in the March 17, 1950 by researchers from the University of California. It has been named to the University of California Name
While in nature [edit]
Although the element does not exist in the ground naturally. However, it exists in the universe emitted in what is known as the electro magnetic supernova
Isotopes
It was discovered nine isotopes him the most stability 251Cf half-life of 898 days and 249Cf half-life 351 years and 250Cf half-life 13 years Other radioactive isotopes have a half-life of less than 2.7 years, and most of them about twenty minutes and the weight of atomic isotopes Atrauah between 237.062 (237Cf) to 256.093 (256Cf).
