Question

One difference between a chemical reaction and a nuclear reaction is that in a nuclear reaction:

a) atoms retain their identity.
b) only the valence electrons are involved.
c) atoms often change from one element to another.
d) only small amounts of energy are absorbed or emitted.

Answer 1

C

Step-by-step explanation:

A nuclear reaction is one in which 2 atoms combine or an atom divides to give rise to entirely different atoms. This is basically the difference it has with a chemical reaction. In a chemical reaction, only new compounds are formed but not new elements. In the case of a nuclear reaction however, even if new elements are not formed, a different atom would be formed.
