simple, the bottom number that is missing is the atomic number. Pu is plutonium which happens to have the atomic number of 94. subtract the top number (mass number) and the atomic number and you get the amount of nuetrons, so the answer is 145 neutrons. (its an isotope)

What kind of rays does uranium 235 and plutonium 239 release?
Plutonium 239 emit: alpha, gamma, spontaneous fission neutrons Uranium 235 emit: alpha, gamma, spontaneous fission neutrons
How many protons and neutrons are in uranium-241?
Uranium is the 92nd element on the periodic table. That means there are 92 protons in 1 uranium atom, no matter which isotope. Protons are constant through an element. Every single atom of Uranium has 92 protons. Neutrons, however change with isotopes. 241 is the number of protons and neutrons together. So subtract 92 from 241 to get the number of neutrons in uranium 241
The plutonium isotope with 145 neutrons?
And what is the question?
How many neutrons in a uranium of 230?
138 neutrons in Uranium-230.
How many neutrons are in a normal uranium atom?
Uranium has 92 electrons and protons.Uranium-234 has 142 neutrons, uranium-235 has 143 neutrons and uranium-238 has 146 neutrons.
Similarties between uranium-235 and plutonium-239 in nuclear reactors?
Uranium 235 and Plutonium 239 are fissile elements, fissionable with thermal neutrons.
What kind of rays does uranium 235 and plutonium 239 release?
