Webb14 okt. 2024 · An electrically neutral uranium-238 isotope contains 92 electrons, 92 protons and 146 neutrons (i.e. e = 92, p = 92, n = 146). So its atomic number is 92 and mass number is 238. Even though uranium is abundantly available on Earth, the uranium-235 isotope has low abundancy (only about 0.72% of the entire Earth’s uranium is U-235). WebbThere are two primary isotopes of uranium, with masses of 235 and 238. Uranium-235 contains 143 neutrons in addition to its 92 protons, while uranium-238 contains 146 … WebbWhat is the mass number of uranium-238? 92 How many protons, neutrons, and electrons are there in an atom of uranium-238? Write the symbol for this isotope. The atomic number of uranium (see periodic table) is 92, and the mass number of the isotope is given as 238. Therefore, it has 92 protons, 92 electrons, and 238 92 : 146 neutrons. indian groceries wholesale suppliers uk
