Question

A- mass no.2 and B- mass no.235, which is suitable for making nuclear reactor and hydrogen bomb

Answer 1

Element B with atomic mass 235 is used for nuclear reactor. Nuclear fission takes place in reactor.

Element A with atomic mass 2 is used for hydrogen bomb. Nuclear fusion takes place in hydrogen bomb

 
.Nuclear fusion is the reaction in which two or more nuclei combine together to form a new element with higher atomic number (more protons in the nucleus).

 
Nuclear fission is the splitting of a massive nucleus into photons in the form of gamma rays, free neutrons, and other subatomic particles.
