Plutonium is a member of the actinide family. The actinides occur in Row 7 of the periodic table. The periodic table is a chart that shows how chemical elements are related to one another. The actinides get their name from element 89, actinium, which is sometimes considered the first member of the family.he half life of a radioactive element is the time it takes for half of a sample of the element to break down. Consider the isotope plutonium-242, with its half life of 376,300 years. In 376,300 years (one half life), only half of a sample prepared today would still be plutonium-242.
This sucker's electrical, but I need a nuclear reaction to- to generate the 1.21 gigawatts of electricity I need.. â Doc and Marty, Twin Pines Mall. Plutonium is a transuranic radioactive chemical element with the chemical symbol Pu and atomic number 94. It was used in the first version of the DeLorean time machine to create the nuclear energy needed (1.21 gigawatts) to create temporal displacement. One pellet of plutonium covered one trip. Dr. Emmett Brown obtained the plutonium from a group of Libyan terrorists who raided a power plant earlier that month, giving them the assurance that he would build them a bomb with it. However, he sent them an empty bomb casing comprised of used pinball machine parts instead.
