1. Question

What is the difference between chemical and nuclear reaction?

In chemical reactions, atoms attempt to achieve stable electron configurations whereas nuclear reaction concerns the nucleus in obtaining a stable nuclear configuration.   
In chemical reactions, atoms attempt to achieve a stable energy emission whereas nuclear reaction concerns particles from an unstable nucleus. 
In chemical reactions, atoms attempt to produce a product of decomposed neutron or proton whereas nuclear reaction concerns the penetration of particles. 
In chemical reactions, atoms attempt to produce a cmoposition of high energy and high speed electron whereas nuclear reaction concerns particles form an unstable nucleus.
