GENERAL KNOWLEDGE

Detailed explanation-1: -A paradigmatic example of nuclear fission processes is uranium 239, an isotope with 92 protons and 147 neutrons that can produce fission if a uranium 238 isotope is bombarded with neutrons.

Detailed explanation-2: -Natural Decay Series of Uranium-238 Uranium has an atomic number of 92 which means there are 92 protons and 92 electrons in the atomic structure. U-238 has 146 neutrons in the nucleus, but the number of neutrons can vary from 141 to 146.

Detailed explanation-3: -There 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 neutrons. Because the two are isotopes of the same element, they behave the same way in chemical reactions.

Detailed explanation-4: -Solution. 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.

Detailed explanation-5: -5) What is U-239? In what ways is it different from U-238? U-239 is an isotope of uranium. It has one more neutron in the nucleus than U-238.
