What element is named after Ernest Lawrence of the University of California Berkeley?
Lawrencium Lr - element number 103 (262Lr)
That element is Berkelium, symbol "Bk" and atomic number 97, a radioactive element in the heavy "actonoid" series. Berkelium is named after the Californian university town of Berkeley where it was first synthesized. Scientists at the University of California's Ernest Orlando Lawrence Berkeley National Laboratory (simply known as "Berkeley Lab") first synthesized Berkelium in 1949. They created it by bombarding a small piece of Americium ("Am" atomic number 95) with alpha particles within a cyclotron.
The 98th element on the periodic table is known as Californium (Cf). It was first made in 1950 at the University of California Radiation Laboratory, in Berkeley. The 97th element on the periodic table was also named after it's original production site. Berkelium (Bk) was discovered in 1949, also at the University of California Radiation Laboratory, in Berkeley.
Elements discovered by Berkeley Lab physicists include astatine, neptunium, plutonium, curium, americium, berkelium*, californium*, einsteinium, fermium, mendelevium, nobelium, lawrencium*, dubnium, and seaborgium*. Those elements listed with asterisks (*) are named after the University, Professors Lawrence and Seaborg.

Berkelium and Californium are named for the University (city) and the state. The elements Lawrencium and Seaborgium are named after Professors Lawrence and Seaborg
Americium was discovered late autumn 1944, at the University of California, Berkeley, by Glenn T. Seaborg, Leon O. Morgan, Ralph A. James, and Albert Ghiorso, while studying transuranic elements as part of the Manhattan Project. They used a 60-inch cyclotron at the University of California, Berkeley. It was named Americium because it lay directly below the already known element Europium on the periodic table.
Plutonium is a man made element it was discovered in Berkeley California. Plutonium was discovered in 1940 by Glenn T. Seaborg, Edwin M. McMillan, Joseph W. Kennedy, and Arthur C. Wahl at the Berkeley Laboratory of the University of California (United States) after the bombardment of uranium with deuterons. Now plutonium is obtained in the nuclear reactors. Uranium minerals are accompanied by plutonium in extremely insignificant traces.
