Mg is radioactive and in the 1950s to 1970s was produced by several nuclear power plants for use in scientific experiments. This isotope has a relatively short half-life (21 hours) and its use was limited by shipping times. The nuclide 26 Mg has found application in isotopic geology, similar to that of aluminium. 26 Mg is a radiogenic daughter ...
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 ...
A mnemonic is a memory aid used to improve long-term memory and make the process of consolidation easier. Many chemistry aspects, rules, names of compounds, sequences of elements, their reactivity, etc., can be easily and efficiently memorized with the help of mnemonics.

Magnesium oxide (Mg O), or magnesia, is a white hygroscopic solid mineral that occurs naturally as periclase and is a source of magnesium (see also oxide).It has an empirical formula of MgO and consists of a lattice of Mg 2+ ions and O 2− ions held together by ionic bonding.
The "hydrogen ion" and the "electron" in these examples are respectively called the "reaction units." By this definition, the number of equivalents of a given ion in a solution is equal to the number of moles of that ion multiplied by its valence. For example, consider a solution of 1 mole of NaCl and 1 mole of CaCl 2.
Magnesium sulfate is usually encountered in the form of a hydrate MgSO 4 ·nH 2 O, for various values of n between 1 and 11. The most common is the heptahydrate MgSO 4 ·7H 2 O , [ 1 ] known as Epsom salt , which is a household chemical with many traditional uses, including bath salts .
Magnesium exists in the upper atmosphere in a variety of different molecular forms. Due to its ability to react with common oxygen and simple carbon-oxygen compounds the magnesium may exist in oxidized compounds including MgO 2, OMgO 2, MgO, and O 2 MgO 2. [10] MgCO 3 + O → MgO 2 + CO 2 OMgO 2 + O → MgO 2 + O 2 MgO + O 3 → MgO 2 + O 2 MgO ...
