Full question: Uranium is an element that is often used in nuclear power plants. Uranium atoms are very large, and the substance can be dangerous if it is not carefully contained. What is true about all uranium atoms?
All uranium isotopes have 92 protons in their nucleus. However, they differ in the number of neutrons in the nucleus, hence this also translates to varying mass numbers (which is the sum of neutrons and protons in the nucleus). The most common isotopes of uranium are; U-238, U-235, and U-234
