The color of chemicals is a physical property of chemicals that in most cases comes from the excitation of electrons due to an absorption of energy performed by the chemical. The study of chemical structure by means of energy absorption and release is generally referred to as spectroscopy .

Simple chemical reactions can be typed out in text. Reactions should be indented using a colon (:), and not centered. Separate the number of molecules from the molecule symbol by a space (i.e. 3 H 2 instead of 3H 2). For example: 2 Na + 2 H 2 O → 2 NaOH + H 2. Reactions in the form of images should also be indented using a colon:
They are text files that represent multiple chemical structure records and associated data fields. The XYZ file format is a simple format that usually gives the number of atoms in the first line, a comment on the second, followed by a number of lines with atomic symbols (or atomic numbers) and cartesian coordinates.
An atom (or ion) whose oxidation number increases in a redox reaction is said to be oxidized (and is called a reducing agent). It is accomplished by loss of one or more electrons. The atom whose oxidation number decreases gains (receives) one or more electrons and is said to be reduced. This relation can be remembered by the following mnemonics.
Red liquid with atomic number 17 and the symbol Y. Makes a compound that is corrosive to copper when mixed with Arsonium and Galine, and an antivirus when mixed with Regalite and Nanite. The real element 17 is chlorine and the element with symbol Y is yttrium. Saronite World of Warcraft: Teal-color metal found in the land of Northrend.
Quantities, Units and Symbols in Physical Chemistry, commonly known as the Green Book, is a compilation of terms and symbols widely used in the field of physical chemistry. It also includes a table of physical constants, tables listing the properties of elementary particles, chemical elements, and nuclides, and information about conversion ...
