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

- Electrons occupy the bulk volume of an atom.
- These particle was discovered by J.J Thomson
- They found orbiting the extra-nuclear space of every atom.
