Which of the following is not a criterion to make a nuclear bomb? A uranium nucleus has 92 protons. 238. Uranium-235 (235 U) is an isotope of uranium making up about 0.72% of natural uranium.Unlike the predominant isotope uranium-238, it is fissile, i.e., it can sustain a fission chain reaction.It is the only fissile isotope that exists in nature as a primordial nuclide.. Uranium-235 has a half-life of 703.8 million years. It is assigned the chemical symbol U. Uranium-235 is an isotope of Uranium-238, all this means is that Uranium-235 has the same number of protons and electrons as Uranium-238, but a different number of neutrons. Uranium is a silvery-white metallic chemical element in the periodic table, with atomic number 92. neutrons = 143 . The atomic number, #Z#, of any element, is the number of protons, positively charged nuclear particles, contained in the nucleus.The mass number (#235#) is the sum of the number of protons, AND the number of neutrons, NEUTRALLY charged nuclear particles.Note that only protons and neutrons contribute to atomic mass to any degree.. You have #""^235U#.If #Z=92# how many neutrons … atomic number and neutrons. 146. A uranium atom has 92 protons and 92 electrons, of which 6 are valence electrons. Uranium has the highest atomic weight (19 kg m) of all naturally occurring elements. Uranium 235, which alone constitutes 0.72% of natural uranium is the second common isotope of uranium in the nature. Tags: Question 5 . All isotopes of uranium are unstable and radioactive, but uranium 238 and uranium 235 have half-lives which are sufficiently long to have allowed them to still be present in the Solar System and indeed on Earth. atomic number and electrons. As all uranium nuclei have 92 protons, the nucleus of a uranium-235 atom will also have 143 neutrons to give it a total atomic mass number of 235. Uranium 235 definition, the radioactive uranium isotope having a mass number of 235, comprising 0.715 percent of natural uranium. 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%). 143. 235 U belongs to primordial nuclides, because its half-life is comparable to the age of the Earth (~4.5×10 9 years). SURVEY . Uranium has 92 protons and either 143 or 146 neutrons, for uranium-235 and uranium-238 respectively. It was discovered in 1935 by Arthur Jeffrey Dempster. Uranium 235. protons, atomic number, and mass number. 92. Q. Get the answers you need, now! What do these isotopes of carbon all have in common? How many neutrons does it have? There are some good answers here, but I'll address uranium specifically. neutrons & mass number. Name: Uranium Symbol: U Atomic Number: 92 Atomic Mass: 238.0289 amu Melting Point: 1132.0 °C (1405.15 K, 2069.6 °F) Boiling Point: 3818.0 °C (4091.15 K, 6904.4 °F) Number of Protons/Electrons: 92 Number of Neutrons: 146 Classification: Rare Earth Crystal Structure: Orthorhombic Density @ 293 K: 18.95 g/cm 3 Color: silverish Atomic Structure See answer the choices are 92, 93, 143, or 235 harmonympaull harmonympaull Answer and Explanation: answer choices . The half-life of uranium 238 is of 4.5 billion years, while uranium 235 has a … 60 seconds . Uranium-238 isotope is most common isotope of uranium found on Earth (about 99.28% of the entire Earth’s uranium is basically U-238). When bombarded with neutrons it undergoes fission with the release of energy. electrons = 92. How many neutrons does it have? How many neutrons does the isotope uranium-235 have - Answer . 55.
