Californium is a radioactive transuranic element, and is 'man-made'. Although it is not naturally occurring on earth, it does seem to come about in other places in the universe (pretty cool, huh?). It is used in starting nuclear reactors and medical treatment of cancer.

∙ 13y agoCalifornium was first synthesized at the University of California, Berkeley by the physics researchers Stanley G. Thompson, Kenneth Street, Jr., Albert Ghiorso, and Glenn T. Seaborg on February 9, 1950.
The reaction to produce this was:-
Curium 242 + Helium 4-------Californium 245 + neutron

Is argon a man made or natural element?
Argon is a natural element found in the air.
What element is found in group 14 and period 5?
Tin
Element that exists as two forms such as diamond or grapite and is found in the human body?
Carbon, it is found in every human cell and as diamonds and graphite
How many elements cant be found in nature?
Uranium, element number 92, is the largest naturally occurring element. However, francium, 87, and astatine, 85, along with any element with an atomic number larger than 92 are not found in nature. They are produced in the laboratory. If they do occur naturally they are in exceedingly small quantities. So to answer your question "How many elements can't be found in nature?" about 16 or a few more.
