Electric charge has several properties. One property of electric charge is that like charges repel one another while unlike charges attract one another. Another property is that electric charge is always conserved. For example, charge will not be created when two initially neutral objects are charged by being rubbed together. The objects are charged when negative charge gets transferred from one object to the other. One object gains a positive charge because it loses an equal amount of negative charge, while the other object gains the lost negative charge. Furthermore, electric charge is quantized. When the charge is quantized, it occurs as discrete bundles in nature, and the charged object never has a fractional charge of ±1.5e.^1. Instead, the object can have a charge of ±e,±2e,or ±3e, etc.
