All the objects from everyday life that we can bump into, touch or squeeze are composed of atoms. This atomic matter is in turn made up of interacting subatomic particles—usually a nucleus of protons and neutrons, and a cloud of orbiting electrons. Typically, science considers these composite particles matter because they have both rest mass and volume. By contrast, massless particles, such as photons, are not considered matter, because they have neither rest mass nor volume. However, not all particles with rest mass have a classical volume, since fundamental particles such as quarks and leptons (sometimes equated with matter) are considered "point particles" with no effective size or volume. Nevertheless, quarks and leptons together make up "ordinary matter", and their interactions contribute to the effective volume of the composite particles that make up ordinary matter.
What kind of particles make up every object in the world that can be touched? The smaller particles that make up atoms, like protons and neutrons, are what kind of particles? What subatomic particle has no volume or rest mass? What  kind of particles are quarks and leptons? Despite not having size or volume themselves, quarks and leptons contribute to what measure of composite particles in matter?
