# uranium 238 protons

Three isotopes of uranium are found in nature, uranium-234, uranium-235, and uranium-238. B) Why They Stay Together In That Tiny Region? A uranium isotope is a specific composition of an atom that qualifies as uranium because it contains 92 protons in its nucleus. uranium 238 protons It is a lanthanide, a rare earth element, originally found in the gadolinite mine in Ytterby in Sweden. Uranium always has 92 protons because that is its atomic number. 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. There are some good answers here, but I'll address uranium specifically. Its chemical properties will be exactly like those of uranium-235. In a nuclear reactor, uranium-238 can be used to breed plutonium-239, which itself can be used in a nuclear weapon or as a reactor fuel source. Uranium-235 is the form commonly used for energy production because, unlike the other isotopes, the

TheÂ chemical symbolÂ for Barium isÂ Ba. Isotopes of Uranium (click to see decay chain): 217 U 218 U 219 U 220 U 221 U 222 U 223 U 224 U 225 U 226 U 227 U 228 U 229 U 230 U 231 U 232 U 233 U 234 U 235 U 236 U 237 U 238 … It participates marginally to the chain reaction, but it nevertheless plays an important auxiliary role. Uranium has an atomic number of 92 which means there are 92 protons and 92 electrons in the atomic structure. The two most common isotopes of uranium are $^{235} \mathrm{U}$ and $^{238} \mathrm{U}$ (a) Compare the number of protons, the number of electrons, … This atom has 92 protons and 146 neutrons. 7. It has an atomic number of 92, meaning that it has 92 protons. So 92U238 238-32 = 206 for mass number. The number of electrons and protons in a neutral atom is always the same, so there are 92 electrons. Beta particles are electrons, the mass of which are negligible on the atomic weight scale. The number of neutrons equals the atomic weight minus the number of protons (238 - 92 = 146). This nuclear reaction may be written. Plutonium-238 was the first isotope of plutonium to be discovered. U-238 has 146 neutrons in the nucleus, but the number of neutrons can vary from 141 to 146. Under these conditions the repulsive force between the protonsis about to defeat the nuclear force. How many neutrons does uranium-238 contain? What are the release dates for The Wonder Pets - 2006 Save the Ladybug? These are uranium-234, uranium-235, and uranium-238. Because atoms of uranium-238 have many more electrons than protons, they release steady streams of electric current. For beta. An alpha particle is a particle that consists of 2 protons and 2 neutrons. The radioactive isotope of uranium is uranium-235. U-238 has 92 protons and (238-92 = 146 neutrons). For alpha. The “238” indicates that the nucleus contains 92 protons and 146 neutrons collectively making a mass of 238. It will contain a different number of protons than an atom of uranium-235. Uranium has 92 protons and either 143 or 146 neutrons, for uranium-235 and uranium-238 respectively. 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. electrons = 92. Uranium-238, for example, accounts for more than 99 percent of all naturally occurring uranium. Big stuff like Uranium usually undergoes alpha particle decay. 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. Uranium is weakly radioactive because all isotopes of uranium are unstable; the half-lives of its naturally occurring isotopes range between 159,200 years and 4.5 billion years. the radioactive uranium isotope having a mass number 238, comprising 99.28 percent of natural uranium: used chiefly in nuclear reactors as a source of the fissionable isotope plutonium 239. 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 So that means Uranium is going to lose two protons and 2 neutrons. In fact, in a typical nuclear reactor, up to a third of the generated power does come from the fission of plutonium-239, which is not supplied as a fuel to the reactor, but transmutedfrom uranium-238. It has an atomic number of 92, meaning that it has 92 protons. What is the number of protons, neutrons, and electrons in uranium-238? 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. This form of uranium that contains a total of 238 nucleons (92 protons and 146 neutrons), is called uranium-238. Its mass will be slightly different from that of an atom of uranium-235. It has a half-life of 4.5 billion years. Because atoms of uranium-238 have many more electrons than protons, they release steady streams of electric current. Uranium: Symbol: U: Atomic Number: 92: Atomic Mass: 238.029 atomic mass units: Number of Protons: 92: Number of Neutrons: 146: Number of Electrons: 92: Melting Point: 1132.0° C: Boiling Point: 3818.0° C Density: 18.95 grams per cubic centimeter: Normal Phase: Solid: Family: Rare Earth Metals: Period: 7: Cost: \$40 per kilogram Nuclides of uranium-238 are extremely stable. - Definition, Types & Examples, Working Scholars® Bringing Tuition-Free College to the Community. The nucleus of tritium (sometimes called a triton) contains one proton and two neutrons, whereas the nucleus of the common isotope hydrogen-1 (protium) contains just one proton, and that of … All Rights Reserved. Nuclei with the same number of neutrons but... How many neutrons does a I^{139} nucleus has? n. chem. The nucleus of a uranium atom contains 92 protons. When you read about the ages of certain ancient artifacts, or even the age of the earth itself, how do we know such numbers? Calculate the average atomic mass of the element.... An element has two isotopes: C-13, and C-12. Answer and Explanation: uranium-238 is the most abundant uranium isotope. Uranium-238 is similar to these isotopes: Isotopes of uranium, Uranium-236, Uranium-234 and more. The mass of a proton and neutron can be said to equal 1, whereas the mass an electron contributes to the atom is negligible (effectively 0). A uranium atom has 92 protons and 92 electrons, of which 6 are valence electrons. Uranium-238 Uranium-235 6. The isotope. Atoms of the same element can belong to different isotopes depending on the number of neutronsthey contain. - Definition & Examples, What Are Valence Electrons?
