Physical Properties: Magnesium is a shiny, silver or gray colored metal that is light in weight and strong. Th density of magnesium is 1.738 g/mL, which means the metal will sink in water, but it is still relatively light weight. Chemical Properties: Magnesium is a silvery white metal.
Aug 17, 2018· The key difference between calcium and magnesium is that the calcium appears as a dull grey metal with a pale yellow tint whereas the magnesium appears as a shiny grey metal. Furthermore, the atomic number of calcium is 20 whereas the atomic number of magnesium is 12. Calcium and magnesium are two chemical elements in the group 2 of the periodic table of elements.
Elements that are placed in the same group in the Periodic Table have similar properties. Magnesium is located in the second group so, elements of this group have similar properties to magnesium. a. Sodium is located in group I, this is not the answer. b. Strontium .

Magnesium react with oxygen at room temperature, forming a passivating layer of MgO on the surface. When ingited, Mg reacts with both oxygen and nitrogen forming a mixture of magnesium oxide, MgO, and magnesium nitride, Mg 3 N 2 [6]. 2 Mg (s) + O 2 (g) 2 MgO (s) 3 Mg (s) + N 2 (g) Mg 3 N 2 (s)
Magnesium is a Group 2 chemical element with symbol Mg & atomic number 12. Know the atomic mass of magnesium, magnesium atomic number and properties of magnesium.
Occurrence, properties, and uses. Known originally through compounds such as Epsom salts (the sulfate), magnesia or magnesia alba (the oxide), and magnesite (the carbonate), the silvery white element itself does not occur free in nature. It was first isolated in 1808 by Sir Humphry Davy, who evaporated the mercury from a magnesium amalgam made by electrolyzing a mixture of moist .
Elements arranged in a group show similar chemical properties because of the presence of same number of valence electrons. We are given: Magnesium is the 12th element of the periodic table having electronic configuration . It has 2 valence electrons. Calcium is the 20th element of the periodic table having electronic configuration
The periodic table, also known as the periodic table of elements, is a tabular display of the chemical elements, which are arranged by atomic number, electron configuration, and recurring chemical properties.The structure of the table shows periodic trends.The seven rows of the table, called periods, generally have metals on the left and nonmetals on the right.
Magnesium is one of the most important elements that is present in many compounds as well as alloys. It is widely used as a chemical reagent, desulfurization agent, and vital ingredient in fireworks. It finds multiple applications due to its unique chemical and physical properties.
Magnesium is the eighth most abundant element in the Earth's crust, but does not occur uncombined in nature. It is found in large deposits in minerals such as magnesite and dolomite. The sea contains trillions of tonnes of magnesium, and this is the source of much of the 850,000 tonnes now produced each year.
Elements are grouped into columns on the periodic table with other elements that have similar chemical properties. Magnesium, with elemental symbol Mg and atomic number 12, is part of group 2 ...
Magnesium, calcium, strontium, barium and radium have similar properties to beryllium. All the elements in group two of the periodic table have the same or similar properties.
Electro-fused magnesium oxide is used for insulating filler of tubular heating elements. To produce a tubular heating element, the coiled electric wire is inserted into the metal tube and the electro-fused magnesium oxide powder is filled into the inside gap.
Oct 01, 2019· The most resemple element of calcium atom is magnesium and Strontium because both are second group elements, and both has similar physical and chemical properties. All the element has similar number of valence electrons. Whereas potassium and scandium do not resample with calcium element because they are different physical and chemical property
Interesting Facts about Magnesium. For many years magnesium was thought to be the same element as calcium. A magnesium fire is very difficult to put out as it can burn in nitrogen, carbon dioxide, and water. It is used in flares and fireworks because of its bright white light when it burns.
Magnesium is a chemical element which is loved by many people because it is used in fireworks and gives bright white light. It is the 18 th most abundant element on our Earth and makes about 13% of the Earth's weight. Magnesium is also an abundant element in seawater after sodium and chlorine elements.
