239 is a Prime Number.
The mass number of plutonium isotopes can vary depending on the specific isotope. Common plutonium isotopes include plutonium-238, plutonium-239, and plutonium-240, with mass numbers of 238, 239, and 240 respectively.
When a fast-moving neutron hits a nonfissionable uranium-238 (U-238) nucleus and is absorbed, an atom of fissionable plutonium-239 (Pu-239) is produced.
U-238 undergoes neutron capture to form U-239 which decays to Np-239 and further to Pu-239. Pu-239 then undergoes beta decay to form Pu-241. The balanced nuclear equation is: U-238 + n --> U-239 --> Np-239 --> Pu-239 --> Pu-241.
Plutonim is obtained from uranium by nuclear reactions: U 238 + 1 neutron → U 239 → Np 239→ Pu 239

Plutonium is primarily synthesized in nuclear reactors through the irradiation of uranium-238 with neutrons. Uranium-238 absorbs a neutron to become uranium-239, which then undergoes two beta decays to form plutonium-239. Plutonium is also produced as a byproduct in nuclear fission reactions.
Adding an extra neutron to Uranium-238 would result in Uranium-239, which is an unstable isotope that will undergo beta decay to form Neptunium-239.
