The number of protons in. the nucleus (called the atomic number) is unique for. each element and largely determines the chemical. behavior of the element. Plutonium has 94 protons. in its nucleus, so it is given the atomic number 94. (There are currently 118 known elements, from.
Both plutonium-239 and plutonium-241 are fissile, meaning that they can sustain a nuclear chain reaction, leading to applications in nuclear weapons and nuclear reactors. Plutonium-240 exhibits a high rate of spontaneous fission, raising the neutron flux of any sample containing it.lutonium was first produced and isolated on December 14, 1940 by Dr. Glenn T. Seaborg, Joseph W. Kennedy, Edwin M. McMillan, and Arthur C. Wahl by deuteron bombardment of uranium-238 in the 60-inch cyclotron at the University of California, Berkeley.
