## anonymous one year ago 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

ok!

4. anonymous

so it is not nuclear fusion? or it is?

5. Michele_Laino

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

6. anonymous

ok! so alpha emission is out! :)

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

9. Michele_Laino

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

10. Michele_Laino

so it is D

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