WebAll isotopes are very slightly radioactive and occur only in traces. Plutonium-238 is composed of 94 protons, 144 neutrons, and 94 electrons. Plutonium-239 is composed of 94 protons, 145 neutrons, and 94 electrons. Plutonium-240 is composed of 94 protons, 146 neutrons, and 94 electrons. WebWe already have two positive charges from our alpha particle, and so we need 90 more. So we need 90 positive charges. We need an atomic number here of 90. The identity of the other product, just look it up here at our table, find atomic number of 90, and you'll see that's thorium here. So thorium-234 is our other product. WebDec 4, 2024 · The atomic number of thorium is 90 and the mass number of thorium is 230 as given in the question. atomic number = number of electrons = number of protons. Therefore the number of electrons in thorium 230 = 90. Number of protons in thorium 230 = 90. Number of neutrons = Mass number - number of protons = 230-90 = 140 raw paws pet food reviews
