What are the quantum numbers of Magnesium? Magnesium atoms in compounds have oxidation states 2. What is the oxidation state of Magnesium? Magnesium has 12 electrons, that is why Magnesium atomic number is 12 and for its electronic configuration you can fill the electrons as per below: The magnesium atom and Na -1, Al +1, Si +2, P +3, S +4, Cl +5 have the same electronic configuration.You can write magnesium electron configuration in short form, i.e.The electronic configuration of magnesium is 1s 2 2s 2 2p 6 3s 2. The chemical element magnesium is distinguished by its atomic number 12, its symbol Mg, and its atomic mass 24.305 u.However, he did not succeed in purifying it completely.įinally, in 1831, the French chemist Antoine Alexandre Brutus Bussy succeeded in developing a method which makes it possible to obtain pure Magnesium. It was only in 1808 that the British chemist Humphry Davy succeeded in obtaining metallic Magnesium by electrolysis of a mixture of Magnesite (MgCO 3 ) and molten Mercury Oxide (HgO). In 1755, the Scottish chemist Joseph Black recognized Magnesium as a chemical element. Initially, the scientist who was the first to successfully isolate pure Magnesium, Humphry Davy, proposed the name "Magnium". The word Magnesium was formed from the word "Magnesia", which is the name of a district of Thessaly, very rich in Magnesium in different forms, and in particular in Magnesium Carbonate. Magnesium is relatively soft silvery-white metal. 12 electrons distributed in the different layers. Its electronic structure is therefore as follows: (K) 2 (L) 8 (M) 2 i.e. Magnesium has two more protons in its nucleus compared to neon. In the periodic table, it is located in the third period and in the second column: it belongs to the alkaline-earth family. Magnesium is a metallic chemical element, with symbol Mg and atomic number Z = 12. The use of food supplements may be necessary, in particular to combat the consequences of a lack of magnesium such as fatigue, stress, anxiety and muscle cramps. Its intake through food is essential but often proves to be insufficient to cover the needs. It participates in more than 300 different reactions, in particular for the transmission of nervous messages, the relaxation of the organism, the formation of bones and teeth and the production of energy.Īs important as it is, magnesium is not produced within the body. Magnesium is an essential trace element in the body. Magnesium is a very popular mineral salt. In atomic form, it appears as a grayish, sparse, easily flammable metal that burns with an intense white glow. Magnesium is the eighth most abundant element in the Earth's layer, and the ninth in the Universe.
