Californium is a synthetic chemical element; it has symbol Cf and atomic number 98. It was first synthesized in 1950 at Lawrence Berkeley National Laboratory ...
Meaning "water-silver", because it is a liquid like water (at room temperature), and has a silvery metallic sheen. ... Californium (Cf) 98 California English
This 1562 map Americae Sive Quartae Orbis Partis Nova Et Exactissima Descriptio by Diego Gutiérrez was the first map to print the toponym California.. Multiple theories regarding the origin of the name California, as well as the root language of the term, have been proposed, [1] but most historians believe the name likely originated from a 16th-century novel, Las sergas de Esplandián.
Californium is the second-heaviest element for which an organometallic compound is known. A bent californium metallocene has also been isolated and characterized.
A minor actinide is an actinide, other than uranium or plutonium, found in spent nuclear fuel.The minor actinides include neptunium (element 93), americium (element 95), curium (element 96), berkelium (element 97), californium (element 98), einsteinium (element 99), and fermium (element 100). [2]
A synthetic element is one of 24 known chemical elements that do not occur naturally on Earth: they have been created by human manipulation of fundamental particles in a nuclear reactor, a particle accelerator, or the explosion of an atomic bomb; thus, they are called "synthetic", "artificial", or "man-made".
118 chemical elements have been identified and named officially by IUPAC.A chemical element, often simply called an element, is a type of atom which has a specific number of protons in its atomic nucleus (i.e., a specific atomic number, or Z).
Californium (98 Cf) is an artificial element, and thus a standard atomic weight cannot be given. Like all artificial elements, it has no stable isotopes. The first isotope to be synthesized was 245 Cf in 1950. There are 20 known radioisotopes ranging from 237 Cf to 256 Cf and one nuclear isomer, 249m Cf.
