Question

Inside of each atom (as tiny as they are) are even smaller individual particles called protons, neutrons, and electrons. Which of these particles has a negative charge?

Tap to reveal answer

Answer

Electrons have a negative charge. The proton moves around the nucleus of an atom, which is in the center. The charge of an electron is opposite but equal to the charge of a proton. Atoms have the same number of electrons as protons. We cannot see these with our eyes, and even with a high-powered microscope, they are too tiny and too low in mass to see.
