Type of particle is a term used to describe the different kinds of particles that make up matter. A boson is a type of particle with an integer spin, such as photons, gluons, and W and Z bosons. Bosons are fundamental particles that mediate interactions between other particles. An ION is a type of particle that has a net electric charge due to the loss or gain of electrons. Ions are formed when atoms or molecules gain or lose electrons, resulting in a charged particle.
