What is a chemical reaction?

A chemical reaction is a process that leads to the chemical transformation of one set of chemical substances to another.

What is nuclear chemistry?

Nuclear chemistry is a sub-discipline of chemistry that involves the chemical reactions of unstable and radioactive elements where both electronic and nuclear changes can occur.

What are reactants or reagents in a chemical reaction?

The substance (or substances) initially involved in a chemical reaction are called reactants or reagents.
