Californium
Californium's Group
Group: Actinides Series
By: Alexandra Krieger
Basic Facts
Symbol:Cf
Atomic Number: 98
Element Name : Californium
Physical Properties
Density: 15.1grams/cm3
Boiling Point: 1472 degrees Celsius
Melting Point: 900 degrees Celsius
State of Matter: solid
Appearance: Silver in color and very shiny
Number of Valence Electrons: 2
Californium's Uses
Group Characteristics:
-Reactivity-radioactive (the atoms of a radioactive element can change into atoms of another element
-solid
-elements with an atomic number higher than 94 are not found in nature

-Can be used to detect metal stress in airplanes
-Provides a large amount of neutrons, enough to start up a nuclear reactor.
-used to mining to discover precious metals such as gold and silver
Because Californium has a large amount of neutrons it used to supply neutrons to machines.
Interesting Facts
-Californium reacts to air and moisture by oxidizing
-Since Californium is man made the most that has ever been created is 10 milligrams
-Californium is created when plutonium is bombarded by neutrons in a nuclear reactor
-Californium only has isotopes, no ions
-Californium was discovered at the University of California, Berkeley in 1950
