Which particle is negatively charged in an atom?

In an atom, the particle that is negatively charged is the electron. Electrons are subatomic particles that orbit the nucleus of an atom, which is made up of protons and neutrons. While protons have a positive charge and neutrons are neutral (having no charge), electrons carry a negative charge. This negative charge allows them to engage in chemical bonding and interactions with other atoms. Thus, the presence of electrons and their charge is fundamental to the structure of atoms and the nature of chemical substances. The balance between positively charged protons and negatively charged electrons defines the overall charge of the atom, leading to stability in the atom when these charges are balanced.
