=Welcome to Mrs. Bowman's Science pages= [|Magnesium] Mg Magnesium’s boiling point is 1994*F and its melting point is 1202*F Magnesium’s density is 1738 Kg m^-3 Magnesium has 12 protons, electrons, and neutrons Its atomic mass is 24.3050 The atomic number is 12 Magnesium has 12 valence electrons

This is the bohr model []

1s2 2s2 2p6 3s2 (orbital notation) In[|1618]an English farmer discovered Magnesium by trying to give his cows water from the well. The cows refused to drink it so he used the water to clean out scratches and clear up rashes. He noticed that the scratches and rashes seemed to heal faster when he put the well water on them. The Epsom salt spread rapidly and soon became known as Magnesium sulfate. It was isolated by Davy in 1808 who electrolyesed the mixture of Magnesium and oxygen creating Mgo, Magnesium Oxide.

[|Physical] properties: Since the density is so heavy, if one were to put Magnesium into water it would sink. Chemical properties: Silvery white metal; the surface of Magnesium is covered with a thin layer of oxide to protect this element from attack of air.

[|Compounds:] Fluorides, Chlorides, Bromides, Iodides, Oxides, Sulfides, Telluride’s, Selenide’s, Nitrides, Carbonyls, and Complexes

[|Magnesium reacts] with air, water, halogens, bases, and acids. When reacting with air, magnesium is created into MgO, Magnesium Oxide, and Mg3N2, Magnesium Nitrate. When reacting with water, magnesium forms Mg (OH) 2, Magnesium Hydroxide. When reacting with halogens, magnesium forms Cl2, Br2, Mgcl2, MgBr2. Magnesium does not create anything new with Bases. Finally, when reacting with acids, magnesium forms H2, which is a hydrogen gas.

[|Magnesium has many uses]; magnesium is used for bombs, flash photography, air craft, car engines, and missile construction. Magnesium reacts with many other things as well. [|The price]of Magnesium depends on what you are using it for. The bigger the object you are building, the higher the price. The price could be anywhere from $22.00 or $216.00. Magnesium is in [|group two]on the periodic table and is called alkaline earth metal. This particular alkaline earth metal is in the s-block on the periodic table. Magnesium is also very important to animals, plants and even humans. For an adult, the requirement is 0.3 grams a day of magnesium. Magnesium is also classified as a metallic bond
