What is the process which causes addition or subtraction of electrons in order to produce a neutral body?

The process of adding or subtracting electrons to achieve a neutral body is known as charge neutralization. When an object gains electrons, it becomes negatively charged, while losing electrons results in a positive charge. To neutralize the charge, the object must either gain or lose electrons until the number of protons (positive charges) equals the number of electrons (negative charges), resulting in an overall neutral charge. This can occur through processes such as conduction, induction, or friction.
