Chemical properties Magnesium is a fairly active metal. The physical properties of the alloys change based on their chemical compositions. It burns with a blinding white light at higher temperatures. However, there are some acid and metal reactions that do not give off hydrogen gas. Calcium's chemical properties are attributed to its location in group 2 of the periodic table. Magnesium is a chemical element with atomic number 12 which means there are 12 protons in its nucleus.Total number of protons in the nucleus is called the atomic number of the atom and is given the symbol Z.The total electrical charge of the nucleus is therefore +Ze, where e (elementary charge) equals to 1,602 x 10-19 coulombs. The most preferred method of anhydrous magnesium chloride preparation is the chemical reaction between magnesium and mercury (II) chloride. Chemical properties of magnesium oxide are similar to the properties of the basic oxides of other metals. Magnesium has two electrons in its outermost shell, giving it an oxidation state of +2. Magnesium and its alloys have very good corrosion resistance and good high temperature mechanical properties. Premier Chemicals, LLC Findlay, Ohio, USA. Aluminium improves strength, hardness and ductility, facilitating the alloy’s casting process. The lubricant properties of the compound were further examined using three hydrates of laboratory-prepared (pure) magnesium stearate. 201935Facts and Info about Magnesium Properties This article on Magnesium properties provide facts and information about the physical and chemical properties of Magnesium which are useful as homework help for chemistry students.
