Which of the following nuclear processes converts light elements into heavier ones?

A.       alpha emission

B.       beta emission

C.       fission

D.       fusion

I think the nuclear fusion, since the nuclear fusion means the fusion of 4 nucleus together, of Hydrogen to get 1 nucleus of Helium

please wait

anonymous · Answer

ok!

anonymous · Answer

so it is not nuclear fusion? or it is?

michele_laino · Answer

alpha emission can not be the right answer since an alpha particle leaves a nucleus, so the final nucleus is lighter than the initial one

anonymous · Answer

ok! so alpha emission is out! :)

anonymous · Answer

what about the others?

michele_laino · Answer

for beta emission, the nuclear process involved is:
$$n \to p + {e^ - } + {\bar \nu _e}$$
now the proton is lighter than the neutron, so also beta emission can not be the right answer

michele_laino · Answer

nuclear fission can not be the right answer, since from one atom of Uranium we get two halves of that atom plus other neutrons

michele_laino · Answer

so it is D

ohh okie! yay!! thank you for the explanations!!:D
