Experts are tested by Chegg as specialists in their subject area.

. U-235 and U-238 are two radioactive isotopes of Uranium. Uranium-235 and U-238 are chemically identical but differ in their physical properties notably their mass. Explain the difference between depleted uranium and enriched uranium Do Format BV Question 31 45 points Explain why the rise in temperature of a lake or river can result in substantial fish kills.

U-235 and U-238 have identical numbers of protons otherwise the element would be different however they have different numbers of neutrons hence the nucleon number is different. See also how is the aztec calendar alike and different from ours. The nuclei of uranium 235 and 238 are along with those of thorium 232 the heaviest present in nature.

But uranium-235 has 143 neutrons and uranium-238 has 146 neutrons. Uranium-235 and uranium-238 has 92 protons and 92 electrons. Uranium-235 and U-238 are chemically identical but differ in their physical properties notably their mass.

The main difference between U-235 and U-238 is that the number of neutrons present in the U-235 nucleus is 143 whereas the number of protons present in the U-238 nucleus is 146. A very small amount 0001 is U-234. Explain in terms of protons and neutrons why U-235 and U-238 are different isotopes of Uranium.

U-235 has 92 protons and 143 neutrons. The number of protons which also give a charge to a nucleus are same in the two which is 92. Uranium-235 has a shorter half-life than Uranium-238.

Because the total number of electrons - the total number of protons. However U-238 is one fertile material and thus it can produce Pu-239 one fissile isotope by nuclear breeding in fast breeder reactor. U-235 and U-238 reffer to atoms of uranuim of different masses.

Though both isotopes were at the time of Earth formation equally abundant natural uranium today consists today of 993 uranium 238 and only 070 uranium 235. The U-238 nucleus also has 92 protons but has 146 neutrons three more than U-235 and therefore has a mass of 238 units.

Uranium-235 and U-238 are chemically identical but differ in their physical properties notably their mass. Same number of protons and different numbers of neutrons. U-235 is 072 of the natural Uranium found.

Uranium-235 235 U is an isotope of uranium making up about 072 of natural uranium. U- 238 does not undergo fission with lower-energy neutrons while U- 235 does. Uranium-235 has 143 neutrons and Uranium-238 has 146 neutrons.

This means they are isotopes of one another. The two have different number of neutrons. U- 235 is a fissile isotope meaning that it can split into smaller molecules when a lower-energy neutron is fired at it.

The half-life of uranium 238 is of 45 billion years while uranium 235 has a half-life of only 700 million years. Uranium-235 has a half-life of 7038 million years. The other 9927 is U-238.

The leftover uranium is primarily uranium-238 referred to as depleted uranium. When uranium-235 is reacted by irradiation with neutrons the uranium atoms split releasing more neutrons heat and atoms with smaller atomic numbers. Explain the difference between depleted uranium and enriched uranium.

Uranium-235 is one fissile isotope thus it can sustain nuclear fission chain reaction with thermal neutron. Explain why molecules do not have electric charges. The difference in mass is minuscule.

Uranium contains primarily two isotopes of interest for nuclear reactions. Uranium-235 is less abundant when compared to Uranium-238. Since atomic mass is a sum of masses of protons and neutrons and we know all have 92 protons we can conclude that they differ textbfdiffer differ.

And separating these isotopes is no easy task. They all have the same number of protons but different numbers of neutrons uranium 238 92 protons 146 neutrons. Therefore fission and alpha decay is more favorable in Uranium-235 compared to Uranium-238.

Uranium-238 From Wikipedia the free encyclopedia Uranium-238 238 U or U-238 is the most common isotope of uranium found in nature with a relative abundance of 99. Unlike uranium-235 it is non-fissile which means it cannot sustain a chain reaction in a thermal-neutron reactor. Who are the experts.

1 HIGHLIGHT TO SEE THE ANSWER. It is the only fissile isotope that exists in nature as a primordial nuclide. Uranium-235 has 235 nucleons and uranium-238 has 238 nucleons.

What is the difference between uranium 235 and 238. What are the similarities and differences between the isotopes. U-238 has 92 protons and 146 neutrons.

Unlike the predominant isotope uranium-238 it is fissile ie it can sustain a nuclear chain reaction. Uranium-235 is slightly lighter than Uranium-238. U235 is the nuclei best suited to nuclear fission which means natural uranium is enriched to raise the percentage of U235 to about 3-5 enriched uraniumthis creates a lot of waste.

The number of protons which also give a. Uranium-235 has 235 nucleons and uranium-238 has 238 nucleons. The U-238 nucleus also has 92 protons but has 146 neutrons three more than U-235 and therefore has a mass of 238 units.

Question 30 45 points Uranium contains primarily two isotopes of interest for nuclear reactions. The difference in mass between U-235 and U-238 allows the isotopes to be separated and makes it possible to increase or enrich the percentage of U-235. Imagine trying to pick out the guys who are.

The aim of nuclear reactors is to generate energy through nuclear fission reactions. The number gives number of nucleons in a nucleus. We review their content and use your feedback to keep the quality high.

What happens when uranium-238 breaks down. Uranium is a chemical element well-known for its radioactive decay. Uranium-238 is not a fissile isotope and thus cannot sustain chain reaction with any neutron.

Uranium 239 uranium 235 uranium 238. The number gives number of nucleons in a nucleus.
