Intro come Chem - arrival

Chemistry is the science of matter, specifically its chemistry reactions, but also its composition, structure and also properties. Chemistry deals with atoms and also their interactions with various other atoms, and an especially with the properties of chemistry bonds. Chemistry likewise involves understanding the properties and also interactions of individual atoms and molecules for use in larger-scale applications.


Classification and also Properties of matter

In chemistry and physics, matter is any substance that has actually mass and takes up space by having volume. All everyday objects that can be touched are ultimately composed of atoms, i beg your pardon are comprised of connecting subatomic particles, and in everyday and also scientific usage, "matter" generally has atoms and also anything comprised of them, and any particles and objects that act together if they have both remainder mass and volume. However it go not encompass massless corpuscle such together photons, or other energy phenomena or tide such together light or sound. Matter exists in miscellaneous states (known as phases) the are identified by assorted physical properties, such together state of matter, phase, shape, and density. The Standard design of particle physics and also the general theory of relativity describe fundamental particles and the basic forces acting in between them that control the structure and also dynamics that matter.
