Matter :- Matter is also used loosely as a general term for the substance that makes up all observable physical objects. The everyday objects that we can bump into 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.
