The name magnesium originates from the Greek word for locations related to the tribe of the Magnetes, either a district in Thessaly called Magnesia [52] or Magnesia ad Sipylum, now in Turkey. [53] It is related to magnetite and manganese, which also originated from this area, and required differentiation as separate substances.
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 magnesium monohydride molecule is a simple diatomic molecule with a magnesium atom bonded to a hydrogen atom. The distance between hydrogen and magnesium atoms is 1.7297Å. [32] The ground state of magnesium monohydride is X 2 Σ +. [1] Due to the simple structure the symmetry point group of the molecule is C ∞v. [32]

Magnesium oxide is the end product of the thermal decomposition of some magnesium compounds and is usually prepared by igniting carbonates or hydroxides. Magnesium hydroxide is a strong electrolyte, which can be obtained by the reaction of a soluble magnesium salt and sodium hydroxide.
the hydrogenation of magnesium anthracene under mild conditions: [5] Mg(anthracene) + H 2 → MgH 2. the reaction of diethylmagnesium with lithium aluminium hydride [6] product of complexed MgH 2 e.g. MgH 2.THF by the reaction of phenylsilane and dibutyl magnesium in ether or hydrocarbon solvents in the presence of THF or TMEDA as ligand.

The magnesium argide ion, MgAr + is an ion composed of one ionised magnesium atom, Mg + and an argon atom. It is important in inductively coupled plasma mass spectrometry and in the study of the field around the magnesium ion. [ 1 ]
Magnesium (12 Mg) naturally occurs in three stable isotopes: 24 Mg, 25 Mg, and 26 Mg. There are 19 radioisotopes that have been discovered, ranging from 18 Mg to 40 Mg (with the exception of 39 Mg). The longest-lived radioisotope is 28 Mg with a half-life of 20.915(9) h.
