All chemical and biological reactions involve the creation and breaking of chemical bonds, which are bonds between the electrons of one atom and the electrons of others.
 
  Given this fact, explain why the electromagnetic force governs all chemical and biological reactions. Also explain why the strong force, the weak force, and gravity play no role in these reactions.

Question 2

Answer to Question 1

Gravity is far too weak to play a role in creating and breaking bonds between atoms or molecules; in fact, its only role in life is in keeping us stuck to the ground. The nuclear forces are of such short range that they have no effects outside the nucleus itself. The only force that remains is the electromagnetic force, which influences interactions between the charged electrons and nuclei. Thus, all events in our ordinary livesall chemistry and biologyare dominated by the electromagnetic force.

Answer to Question 2

C
