It provides atomic mass, mass excess, nuclear binding energy, nucleon separation energies, Q-values, and nucleon residual interaction parameters for atomic nuclei of the isotope Pu-239 (Plutonium, atomic number Z = 94, mass number A = 239).Related documents Landolt-Brnstein Homepage Introduction ...
noun Chemistry, Physics. a transuranic element with a fissile isotope of mass number 239 (plutonium 239 ) that can be produced from non-fissile uranium 238,
plutonium-239, readily undergoes fission and is used as a reactor fuel in nuclear power stations and in nuclear weapons. Symbol: Pu; atomic no: 94; half-life of239Pu: 24 360 years; valency: 3, 4, 5, or 6; relative density (alpha modification): 19.84; melting pt: 640°C; boiling ...
Isotopes:Plutonium has 17 whose half-lives are known, with mass numbers from 227 to 248. None are stable. Its longest lived isotopes are244Pu, with a half-life of 80.8 million years,242Pu with a half-life of 373,300 years and239Pu with a half-life of 24,110 years. ...
By the same token, Pu-238 and Pu-239 behave differently in nuclear reactions as well. Pu-239 is fissile like U-235. That means it can be used in bombs and reactors. In fact, the atomic bomb dropped on Nagasaki, nicknamed “Fat Man”, was a plutonium bomb. ...
Is plutonium (element 94) a metal, properties (atomic mass, how does it look like, density, atomic number, electron configuration), common uses, price
The atomic bomb dropped on Nagasaki, Japan in 1945 had a plutonium core. The isotope plutonium-239 is a key fissile component in nuclear weapons, due to its ease of fission and availability. Encasing the bomb's plutonium pit in a tamper (an optional layer of dense material) decreases the...
