Which of the following BEST describes what occurs in a fusion reaction?

Question

a
Electrons are shared between the nuclei.

b
Two low mass nuclei are joined to form one nucleus and gives off energy.

c
A chemical reaction occurs between the nuclei.
d
A single nucleus divides into two or more nuclei and gives off energy.

Answer 1

The option that BEST describes what occurs in a fusion reaction is:

b Two low mass nuclei are joined to form one nucleus and gives off energy.

In a fusion reaction, light nuclei combine to form a heavier nucleus, and this process releases a significant amount of energy.
