First made in 1950 at the University of California. It is a radioactive metallic chemical element
The element 98 - californium (Cf) - was discovered in 1950 by Glenn Seaborg, Stanley Thompson, Albert Ghiorso, Kenneth Street et alii.
it wasnt discovered it was made (any element after uranium is human made)
What element are you asking for? Elements can be made by nature or humans.
Technetium which has an atomic mass of 98.
No one makes any element! they are naturally occurring! If your asking about who discovered it the answer is No one is sure. It was discovered so long ago that no one knows who discovered it!
No one made elements they only discovered them
Aluminum. It was identified as an element discovered in 1872
The most metallic element on the planet is Francium. It is the last element to be discovered that was not made synthetically.
This element is technetium (Tc); but today traces of natural technetium were discovered.
Californium is the only element named after a U.S. state. Its atomic number is 98.It's radioactive and was discovered in Berkeley university and named after California.
The element argon was discovered in 1894.
The latest confirmed element discovered was Livermorium, 116Lv, in 2000. Ununseptium is not officially credited as "discovered" by the IUPAC/IUPAP Joint Working Party, but it is the most recently synthesized element, made in 2010.
