Plutonium has six allotropes at ambient pressure: alpha (α), beta (β), gamma (γ), delta (δ), delta prime (δ'), and epsilon (ε). [13] Plutonium normally has six allotropes and forms a seventh (zeta, ζ) at high temperature within a limited pressure range. [13]
21 Mei 2024 · plutonium (Pu), radioactive chemical element of the actinoid series of the periodic table, atomic number 94. It is the most important transuranium element because of its use as fuel in certain types of nuclear reactors and as an ingredient in nuclear weapons.
13 Dis 2021 · Virginia Grant Writer. The element plutonium was discovered only 81 years ago, but its impact on the world has been monumental. On December 14, 1940, chemist Glenn Seaborg and his colleagues at the Berkeley Radiation Laboratory used a 60-inch cyclotron to bombard the element uranium with deuterons.
19 Sep 2014 · Plutonium may be the most feared and fearsome substance in the entire periodic table. It's best known as the main ingredient of atomic bombs like the infamous Fat Man, dropped on Nagasaki on 9 ...

7 Jan 2021 · Backgrounder on Plutonium. Printable Version. Plutonium is a radioactive metallic element with the atomic number 94. It was discovered in 1940 by scientists studying how to split atoms to make atomic bombs. Plutonium is created in a reactor when uranium atoms absorb neutrons.
Effects after inhalation. Plutonium is most dangerous after inhalation. The solubility of the plutonium compounds determines how long the plutonium stays in the lung. A number of physical, chemical, and biological factors influence the retention time, which can be between about 100 and 10,000 days.
19 Mac 2020 · What is Plutonium? Printable Version. Plutonium has five "common" isotopes, Pu-238, Pu-239, Pu-240, Pu-241, and Pu-242. All of the more common isotopes of plutonium are "fissionable"—which means the atom's nucleus can easily split apart if it is struck by a neutron. The various isotopes of plutonium have been used in a number of applications.
11 Okt 2022 · Plutonium is the 94th element in the periodic table and one of the most dangerous elements on Earth. Here we explore Plutonium in more detail.
