Charge Units, Conservation, and Quantization
➢ Two types of charges exist (positive and negative)
➢ Like charges repel and unlike charges attract one another
➢ Nature’s basic carrier of positive charge is the proton
• Protons do not move from one material to another because they are held firmly in the nucleus
➢ Nature’s basic carrier of negative charge is the electron
• Gaining or losing electrons is how an object becomes charged
