Define nuclear decay and chemical change. What is the key difference between the two processes?.
Model answer
What a good answer should say
- Nuclear decay is the process by which an unstable atomic nucleus loses energy by emitting radiation, resulting in a change in the nucleus itself.
- Chemical change involves the rearrangement of atoms to form new substances without altering the nuclei of the atoms.
- The key difference is that nuclear decay changes the identity of the element, while chemical change does not.
Explanation
