nuclear fission and fusion reactions give off energy becaus?

Question

a. the binding energy per nuleus is least for nuclie of intermeediate size
b. the binding energy per nuleus is greater for nuie of intermediate size
c. they result in the production of neutrons
d. they result in the prouction of plutonium

Answer 1

hey
the correct answer is

b. the binding energy per nuleus is greater for nuie of intermediate size


make sure ure basic concepts are clear ......
i will explain u the meanings properly..

nuclear fusion is the process by which multiple atomic particles join together to form a heavier nucleus. It is accompanied by the release or absorption of energy. Iron and nickel nuclei have the largest binding energies per nucleon of all nuclei and therefore are the most stable. The fusion of two nuclei lighter than iron or nickel generally releases energy while the fusion of nuclei heavier than iron or nickel absorbs energy; vice-versa for the reverse process, nuclear fission.


Nuclear Fission is the process of splitting an atom to create an explosion. This process is less powerful than the fusion bombs such as the hydrogen bomb. A uranium bomb is a form of a fission bomb - when a neutron is shot through the nucleus of the atom, the atom breaks up into 2 separate elements: Krypton and Barium. These are called the "daughters" of the nucleus.

hope this is the best answer...
all the best........

Answer 2

b)because then only it will be spontaneous otherwise it will be endothermic(second law of thermodynamics).it is 8.1mev per neucleon for stable nucleus range from iron to molybdenum.

Answer 3

fission and fusion are different processes, all four choices are wrong.
