Which particle in an atom is negatively charged?

In an atom, the particle that carries a negative charge is the electron. Electrons are subatomic particles that orbit the nucleus of an atom and are fundamental to the process of chemical bonding and electrical conductivity. Their negative charge plays a critical role in the interactions between atoms, influencing how they connect to form molecules.

The nucleus, on the other hand, contains protons and neutrons. Protons are positively charged, while neutrons are neutral, having no charge at all. The balance of protons and electrons in an atom determines its overall electrical neutrality and defines its chemical properties. Therefore, it is the electron that is specifically identified as the negatively charged particle in the atom.
