# uranium 235 protons

""_92^238"U" ""_92^235"U" The isotopic symbol (also called nuclear notation) includes the chemical symbol of the element, the mass number for the particular isotope, and the atomic number (number of protons) of the element. However, it is fissionable by fast neutrons, and is fertile, meaning it … yeah, look on the periodic table. The neutron number = the … Explanation: to find out the no neutrons . 9 Answers. 92. 143 neutrons..... anasg0508 anasg0508 Answer: 143. Its isotopic symbol is ""_92^238"U" . Example; uranium-235 has 92 protons so it’s proton number is 92. If there are too many or too few neutrons for a given number of protons, the resulting nucleus is not stable and it undergoes radioactive decay. Uranium-238 is the most common isotope of uranium found in nature, with a relative abundance of 99%. Lv 7. The next most likely provision is a uranium nucleus that contains three fewer neutrons: uranium-235. Uranium-235 is an isotope of uranium making up about 0.72% of natural uranium. When the nucleus of a U-235 atom captures a moving neutron it splits in two (fissions) and releases some energy in the form of heat, also two or three additional neutrons are thrown off. This isotope has half-life of 7.04×10 8 years (6.5 times shorter than the isotope 238) and therefore its abundance is lower than 238 U (99.28%). Uranium-235 makes up about 0.72% of natural uranium. cunny. Uranium-235 has 235 Pa, 235 Np, and 239 Pu as its parent isotopes. Uranium 235 has 92 protons in its atom. In the process of splitting, a great amount of thermal energy, as well as gamma rays… This is the number of protons. Calculate the numbers of neutrons in the isotopes uranium-235 and uranium-238. The number of neutrons = A - Z = 235 - 92 = 143. Textbook solution for Glencoe Physics: Principles and Problems, Student… 1st Edition Paul W. Zitzewitz Chapter 30 Problem 49A. uranium-235, and uranium-238. • Uranium-235 is less abundant when compared to Uranium-238. Thank you so much for your help in advance :) 235 and 238 are the mass numbers (or nucleon number) of two of its isotopes. U is element 92 so it has 92 protons and 92 electrons . write any key point about heat? The nucleus of the U-235 atom comprises 92 protons and 143 neutrons (92 + 143 = 235). Terbium is a silvery-white, rare earth metal that is malleable, ductile, and soft enough to be cut with a knife.
