A negative charge refers to an electrical property of particles, such as electrons, that causes them to attract positively charged particles, like protons. This charge is a fundamental aspect of electricity and is responsible for the interactions between atoms and molecules. In simple terms, negative charges can be thought of as a type of energy that can influence how objects behave when they come close to each other. In everyday life, negative charges are commonly observed in static electricity. For example, when you rub a balloon on your hair, electrons transfer from your hair to the balloon, giving the balloon a negative charge. This causes the balloon to attract your hair or other lightweight objects, demonstrating the effects of negative charge in action.
