matter
Condensed matter physics deals with the physical properties of condensed phases of matter. These properties appear when a number of atoms at the supramolecular and macromolecular scale interact strongly and adhere to each other or are otherwise highly concentrated in a system. The most familiar examples of condensed phases are solids and liquids.
An illustration of the helium atom, depicting the nucleus (pink) and the electron cloud distribution (black). The nucleus (upper right) in helium-4 is in reality spherically symmetric and closely resembles the electron cloud, although for more complicated nuclei this is not always the case.
All types of hadrons always have zero total color charge.
One contemporary view on matter takes it as all scientifically observable entities whatsoever. Commonly, the definition is limited to such entities explored by physics.
