The most common isotope of uranium is uranium-238. To find the number of neutrons in this isotope, you can use the formula:

Calculating Neutrons

The number of neutrons is determined by subtracting the atomic number from the atomic mass:

  • Atomic Mass of Uranium-238: 238
  • Atomic Number of Uranium: 92

Using the formula:

Neutrons = Atomic Mass - Atomic Number

So, for uranium-238:

Neutrons = 238 - 92 = 146

Final Answer

The most common isotope of uranium, uranium-238, has 146 neutrons.
