Atomic physics - nuclear fission

  1. The problem statement, all variables and given/known data
    1. Which of the following statements is / are not correct?

    (1) In fission, two large fragments of equal masses are produced from a nuclide.
    (2) Natually occurring elements perform fission spontaneously.
    (3) 2 H2O --> 2H2 + O2 involves nuclear fission.




    2. Relevant equations

    /

    3. The attempt at a solution
    3. It's a MC question and the answer is

    D (1), (2) and (3)

    My question is: I don't understand the meaning of statement (2).
    Thus I 've got a wrong answer.
    Can anyone please kindly explain to me ?

    Do you know what a naturally occurring element is? How would you define a naturally occuring element?
