Chemistry is the physical science which examines the composition, structure, properties and behavior of matter. It focuses on atoms, their interactions with other atoms and phenomena such as the forming of chemical bonds between atoms to create chemical compounds. In chemistry, matter is defined as anything that has rest mass and volume (it takes up space) and is made up of particles.
