uranium 238 protons

What's X? 238 92 U + 2 1 H → 238 93 Np + 2 n + e + + ν e One mole of U238 ( 6.022 X 10^23 atoms) is 238 grams; one mole of U235 is 235 grams. They can absorb large amounts of energy without breaking apart, so they rarely need to be replaced. Uranium 238, which alone constitutes 99.28% of natural uranium is the most common isotope of uranium in the nature.This isotope has the longest half-life (4.47×10 9 years) and therefore its abundance is so high. This nuclear reaction may be written. An alpha particle is a particle that consists of 2 protons and 2 neutrons. Since we know that this particular isotope of uranium has a combined total of 238 protons and neutrons, the total number of neutrons in 238U is 238 - 92 = 146.Uranium 238 has: 92 protons, 92 electrons and 146 neutrons. Also called U 238, U 238. U238 has 92 protons and 146 neutrons. The element, uranium, has an atomic number of 92. explain why molecules do not have electric charges. The electrons can be found in spaces called orbitals. III. Start with a uranium-238 atom. Alpha particles are helium nuclei each made up of two protons and two neutrons. ²³⁵U A definite ratio of neutron to proton in the nucleus makes the nucleus stable. The “238” indicates that the nucleus contains 92 protons and 146 neutrons collectively making a mass of 238. Atoms of the same element can belong to different isotopes depending on the number of neutronsthey contain. B) Why They Stay Together In That Tiny Region? It has an atomic number of 92, meaning that it has 92 protons. Uranium has 92 protons in its nucleus. Uranium is atomic number 92 - this means it has 92 protons - which in a neutral atom means it also has 92 electrons. That means that, assuming it's electrically neutral, it has 92 protons and 92 electrons. Love, Dipti Patel: H. Sela, Z. Karpas, C. Pickhardt, J.S. When it decays it emits an alpha particle, leaving behind a thorium-234 atom. Uranium (92 U) is a naturally occurring radioactive element that has no stable isotope.It has two primordial isotopes, uranium-238 and uranium-235, that have long half-lives and are found in appreciable quantity in the Earth's crust.The decay product uranium-234 is also found. If there are 146 neutrons in the nucleus of the uranium atom, it is in an unstable situation. A. U-238 has three more electrons than U-235. Uranium 238. Uranium 235 vs Uranium 238 Uranium is a heavy metal element abundant in the earth’s core. These are uranium-234, uranium-235, and uranium-238.

In the spaces provided, write the symbols for the nucleus of each isotope of uranium. All rights reserved. Answer and Explanation: uranium-238 is the most abundant uranium isotope. A single nucleon (proton or neutron) has a radius of about 1 10 −15 m. (a) Calculate the approximate radius of the uranium nucleus.

All of the alkali metals have a single valence electron in the outer electron shell, which is easily removed to create an ion with a positive charge â a cation, which combines with anions to form salts. So that means Uranium is going to lose two protons and 2 neutrons. 2. All Rights Reserved. It has an atomic number of 92, meaning that it has 92 protons. These numbers refer to the number of neutrons and protons in each atom. An electrically neutral uranium-238 isotope contains 92 electrons, 92 protons and 146 neutrons (i.e. b) Why they stay together in that tiny region? The number of neutrons equals the atomic weight minus the number of protons (238 - 92 = 146). The number of electrons and protons in a neutral atom is always the same, so there are 92 … U-238 has 146 neutrons in the nucleus, but the number of neutrons can vary from 141 to 146.
