What type of particle has an antimatter equivalent with an opposite charge but identical mass?

The concept of antimatter refers to particles that have the same mass as their corresponding matter counterparts but have opposite charge and quantum numbers. A prime example is the electron and its antimatter equivalent, the positron. The positron has the same mass as the electron but a positive charge, which is opposite to the negative charge of the electron.

The term "antimatter" encompasses a range of particles, each having an equivalent particle in the matter category with identical mass and opposite charge. Therefore, when considering a type of particle that has a defined antimatter equivalent, the term "antimatter" accurately encapsulates this relationship, highlighting the fundamental symmetry observed in particle physics.

Other options do not apply in this context. Photons, for example, are massless carriers of electromagnetic force and do not possess a charge, making them distinct from particles that have charged antimatter equivalents. Bosons are force carrier particles and can include both matter and antimatter but do not have the same direct one-to-one correspondence in terms of charge as seen with particles like electrons and positrons. Fermions are a broader classification that includes particles such as electrons and quarks, but the specific term "antimatter" directly addresses the query about the particle having an
