A typical nuclear fission reactor contains a mix of uranium and plutonium isotopes, such as uranium-235 and plutonium-239.
Fill in the following:
Uranium-235:
Number of protons –
Number of neutrons –
Number of electrons – 92
Uranium-233
Number of protons –
Number of neutrons – 141
Number of electrons –
Plutonium-239
Number of protons – 94
Number of neutrons –
Number of electrons –
Plutonium-239 is present in nuclear reactors as the oxide, PuO2.
Calaculate the percentage by mass of plutonium in PuO2.
O, 16; Pu, 239
