Charge (-e)
Definition
Charge refers to one of the fundamental properties of matter that determines how objects interact with electromagnetic fields. A negative charge (-e) indicates an excess or deficit of electrons compared to protons within an object.
Analogy
Imagine a group of friends playing a game of tag. If one person is "it" and has a negative charge, it means they have more tags than the others. They will try to pass on their excess tags by tagging other players.
