Question

The binding energies of a deutron and an $\alpha$ -particle are 1.125, 7.2 MeV/nucleon respectively. Which is more stable of the two?

• A. deuteron
• B. $\alpha$-practicle
• C. both
• D. sometimes deutron and sometimes $\alpha$ -particle

Answer 1

Answer: (B)

$\alpha$-practicle

The binding energy is a energy that holds the nucleus together.

Thus, more binding energy will give more stable nuclei. Here alpha particle has more binding energy so it will be more stable than deutron.
