Nuclear stability

Question

Why is a fusion reaction difficult to perform?

Easy

A

The nuclei are set up far from each other
B

The attraction between the nuclei
C

Sun’s energy is not sufficient
D

Repulsion between the nuclei

Solution

For the fusion reaction to occur, the light nuclei are brought closer to each other, at a distance of about 10^-14 m. This is only possible at a very high temperature to counter the repulsive force between the two nuclei. Due to this reason, the fusion reaction is difficult to perform.
