Chemical equation carbon dating
Each of the elements involved in the reaction is identified by the chemical symbol. The number at the upper right is the mass number, also known as the A number.
We commonly express these reactions by equations, although there is a unique difference in the nature of the reactions.
The principle difference between them lies in how the reaction occurs, specifically how the atom is affected.
Chemical reactions involve an atoms electrons while nuclear reactions involve the atoms nucleus.
In order to write an equation for a nuclear reaction, we must first establish some basic rules.
Uranium-238 is an isotope, which undergoes alpha decay to produce Thorium and gamma rays.
This is expressed mathematically by the following equation: Note that when the mass numbers on each side of the equation are added together that they are equal.
