Question

Why do only big nuclei undergo nuclear fission reaction?

• A. Bigger nuclei are unstable because of presence of large number of like charge particles.
• B. Bigger nuclei have very less number of protons which makes them unstable.
• C. Bigger nuclei have less number of neutron which makes them unstable.
• D. In case of bigger nuclei, electron reside inside the nucleus.

Answer 1

The correct option is A

Bigger nuclei are unstable because of presence of large number of like charge particles.

Large nuclei have a large number of like charge particles close to each other and hence they are unstable in nature. Because of this instability, they undergo nuclear fission reaction to form two stable nuclei.
