Uranium is a metallic element that is used in nuclear reactors and nuclear weapons. The vast majority of uranium found on Earth is in the form of uranium-238, an isotope with a mass number of 238, while the uranium that is used for nuclear reactors and weapons is uranium-235, an isotope with a mass number of 235.
-What is the atomic difference between uranium-235 and uranium-238?

Question

Quizplus · Accepted Answer

The difference between uranium-235 and uranium-238 is that uranium-235 has three fewer neutrons than uranium-238. They both have the same number of protons and electrons, but differ in their number of neutrons, which gives them different atomic masses.
