The model below represents a nuclear reaction. atom 1 is present before the reaction and atom 2 and atom 3 are produced after the reaction.

atom 1 = atom 2 + atom 3 + energy

the model most likely represents a reaction which
select one:
a. takes place when atoms combine
b. takes place when atoms become inactive
c. does not produce energy in the sun
d. does not produce energy in nuclear power plants
