What particle in an atom has a negative charge?

The particle in an atom that has a negative charge is the electron. Electrons are fundamental components of atoms, typically found in energy levels surrounding the nucleus, which consists of protons and neutrons. The negative charge of electrons is crucial in determining how atoms interact and bond with each other, contributing to the chemical properties of elements.

Protons, on the other hand, carry a positive charge and are located within the nucleus. Neutrons have no charge, making them electrically neutral, and they also reside in the nucleus alongside protons. An alpha particle, which consists of two protons and two neutrons (essentially a helium nucleus), also carries a positive charge. Thus, the electron stands out as the only particle among the options with a negative charge.
