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 .
It is best to choose background colors that offer sufficient contrast in relation to text and blue links, which is also the color of references, both of which are very common in most articles. Use the WCAG link contrast checker to ensure that the chosen background color offers the recommended WCAG AA level of contrast against normal text ...

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.
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.

This glossary of chemistry terms is a list of terms and definitions relevant to chemistry, including chemical laws, diagrams and formulae, laboratory tools, glassware, and equipment. Chemistry is a physical science concerned with the composition, structure, and properties of matter , as well as the changes it undergoes during chemical reactions ...
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:
