Plutonium-238 has 144 neutrons, plutonium-240 has 146 neutrons.
Atomic Mass and half life are also different.
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.
Directly, no. Once fissioned the plutonium is gone (it has transformed to other lighter elements). However indirectly using a breeder reactor, yes. A plutonium fueled breeder reactor with a uranium breeding blanket will produce more plutonium (from uranium-238) than it consumes. This breeder reactor can at the same time be generating electricity like any other power reactor.
Typically, a nuclear bomb would use plutonium-239 as the primary isotope for fission. Plutonium-239 is preferred due to its high fissionability and ease of obtaining through processing in nuclear reactors. Small amounts of other plutonium isotopes, such as plutonium-240, may also be present due to the manufacturing process, but the majority would be plutonium-239.
The difference between 220 amps and 240 amps lies in their amperage ratings. 220 amps denotes a current capacity of 220 amperes, while 240 amps indicates a current capacity of 240 amperes. The higher the amperage, the greater the power capacity for electrical devices.
Uranium 240 has 92 protons and electrons, but 148 neutrons because the atomic number is 92 and the atomic mass is 240.
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.
- Plutonium-238: from the beta double-decay of U-238 - Plutonium-239: from a nuclear reaction of U-238 with neutrons (neutrons from a spontaneous fission) - Plutonium-240: a radioactive decay product of Pu-244 - Plutonium-244: it is considered a primordial isotope for the Earth All these isotopes (of natural origin) exist in uranium ores in infinitesimal but today detectable concentrations.
- Natural plutonium (plutonium isotopes 238, 239, 240, 244) exist in nature as extremely traces associated with uranium ores- Artificial isotopes of plutonium (the most important being Pu-239) have the origin in nuclear weapons tests

The obvious difference is a plutonium weapon uses plutonium as its fuel while a uranium weapon uses uranium as its fuel, however there are also composite weapons that use both as their fuel. Plutonium, being produced in reactors has some degree of plutonium-240 and plutonium-241 as undesired contaminates that can cause a fizzle. So weapons made with plutonium must be assembled much more rapidly than uranium weapons. So uranium weapons can use either gun or implosion rapid assembly systems, but weapons using any amount of plutonium must use implosion rapid assembly systems.
The isotope symbol of plutonium with 146 neutrons is plutonium-246, represented as ^246Pu.
The differencs is 240 minus 137 equals 103
