* Electrons carry mass: Electrons, which carry a negative charge, have a tiny but measurable mass.
* Adding electrons, adding mass: When an object gains a negative charge, it's essentially gaining extra electrons. These added electrons increase the object's overall mass, albeit by a minuscule amount.
Important Note: The mass increase due to gaining a negative charge is incredibly small. It's not something you'd notice in everyday objects. The increase is only significant when dealing with extremely high charges or at the atomic level.
