Question

Which of the following statements is not true of the process of nuclear fission? (3 points) It is the process used in most nuclear power plants. It only occurs in very small atoms with low mass. It involves the splitting of an atom's nucleus. It can occur in a chain reaction.

Answer 1

Nuclear fission does not only occur in very small atoms with low mass.

So the false answer is the second one It only occurs in very small atoms with low mass

Answer 2

Answer: the statement that is not true is the second one: It only occurs in very small atoms with low mass.

Step-by-step explanation:

The nuclear fission consists in the division or fragmentation of an atomic nuclei into smaller fragments releasing huge amounts of energy.

The biggest and heaviest atoms are unstable, meaning that they gain stability by splitting into smaller, lighter atoms.

So, the third given statement contradicts the previous fact.

That is why most of the heaviest elements have not been found naturally but have been created synthetically and have very short life times.
