Identify the characteristics of an unstable nucleus.

[Mark all correct answers]

A. Does not have enough binding energy.
B. Can hold the nucleus permanently.
C. Cannot hold the nucleus permanently.
D. Emits alpha, beta, or gamma radiation.



Answer :

Final answer:

Unstable nuclei lack sufficient binding energy, leading to radioactive decay where they emit alpha, beta, or gamma radiation.


Explanation:

Characteristics of an unstable nucleus:

  • Does not have enough binding energy: Unstable nuclei have insufficient binding energy per nucleon, making them less stable.
  • Cannot hold the nucleus permanently: Unstable nuclei are prone to disintegration or radioactive decay.
  • Emits alpha, beta, or gamma radiation: Unstable nuclei emit these types of radiation during decay processes.
