In terms of particle arrangement, the state of matter where the particles are least tightly arranged is the gas state. In gases, particles are far apart and move freely, whereas in solids, particles are closely packed in a fixed arrangement, and in liquids, they are less tightly packed compared to solids but still closer than in gases.
