What effect does an unstable nucleus have on its surroundings?.
- A.It remains unchanged
- B.It can cause ionization in nearby materials
- C.It absorbs energy from the environment
- D.It increases the mass of surrounding particles
Model answer
What a good answer should say
- It can cause ionization in nearby materials
Explanation
Why this works
An unstable nucleus can cause ionization in nearby materials as it emits radiation during decay. This radiation can interact with surrounding atoms, knocking electrons off and creating ions.
The consequence of this ionization can lead to chemical changes in materials and potential biological effects, making the understanding of unstable nuclei crucial in fields like radiation safety and nuclear physics.
