Mn(IV) is somewhat enigmatic because it is common in nature but far rarer in synthetic chemistry. The most common Mn ore, pyrolusite, is MnO 2. It is the dark brown pigment of many cave drawings [31] but is also a common ingredient in dry cell batteries. [32] Complexes of Mn(IV) are well known, but they require elaborate ligands.
Manganese, symbol Mn, a chemical element.mn, the Internet country code top-level domain for Mongolia; Mega newton (MN), a unit of force equal to one million newtons; milli newton (mN), one-thousandth of a newton; Membranous nephropathy; Minimum mode, a hardware mode available to Intel 8086 and 8088 processors; Number average molecular weight (M n)
The purpose, rather than to standardize state abbreviations per se, was to make room in a line of no more than 23 characters for the city, the state, and the ZIP code. [4] Since 1963, only one state abbreviation has changed.
Also acid ionization constant or acidity constant. A quantitative measure of the strength of an acid in solution expressed as an equilibrium constant for a chemical dissociation reaction in the context of acid-base reactions. It is often given as its base-10 cologarithm, p K a. acid–base extraction A chemical reaction in which chemical species are separated from other acids and bases. acid ...
Chemical symbols are the abbreviations used in chemistry, mainly for chemical elements; but also for functional groups, chemical compounds, and other entities. Element symbols for chemical elements, also known as atomic symbols , normally consist of one or two letters from the Latin alphabet and are written with the first letter capitalised.

Neutral atoms of the chemical elements have the same term symbol for each column in the s-block and p-block elements, but differ in d-block and f-block elements where the ground-state electron configuration changes within a column, where exceptions to Hund's rules occur. Ground state term symbols for the chemical elements are given below.
The Minnesota functionals are available in a large number of popular quantum chemistry computer programs, and can be used for traditional quantum chemistry and solid-state physics calculations. These functionals are based on the meta-GGA approximation , i.e. they include terms that depend on the kinetic energy density, and are all based on ...
