Question

Which of the following is true for a sample of isotope containing straight U to the power of 235 and straight U to the power of 238

  1. Number of neutrons are same in both
  2. Number of protons, electrons and neutrons are same in both
  3. Contain same number of protons and electrons but straight U to the power of 238 contains 3 more neutrons than straight U to the power of 235
  4.  straight U to the power of 238contains 3 less neutrons than straight U to the power of 235

The correct answer is: Contain same number of protons and electrons but straight U to the power of 238 contains 3 more neutrons than straight U to the power of 235
