This metal is very reactive when exposed to air; it forms a dark oxide-nitride layer. Calcium is a chemical element having the atomic number 20 and chemical symbol Ca. @media (max-width: 1171px) { .sidead300 { margin-left: -20px; } } 2. This element occurs in a solid phase at standard temperature and pressure. It locates in the group 2 and period 3 of the periodic table. Magnesium is a silvery-white, low density, reasonably strong metal that tarnishes in air to form a thin oxide coating. The electron configuration of magnesium is [Ne] 3s2. Furthermore, the atomic number of calcium is 20 whereas the atomic number of magnesium is 12. Calcium metal appears as a dull grey metal with a pale yellow tint. Magnesium (Mg), chemical element, one of the alkaline-earth metals of Group 2 (IIa) of the periodic table, and the lightest structural metal. Its compounds are widely used in construction and medicine, and magnesium is one of the elements essential to all cellular life. 2. The atomic number of calcium is 20 whereas the atomic number of magnesium is 12. 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. Moreover, magnesium (+2) cation is the second most abundant cation in seawater. Copyright, ownership information and cookies- and privacy policy. Madhu is a graduate in Biological Sciences with BSc (Honours) Degree and currently persuing a Masters Degree in Industrial and Environmental Chemistry. 1. Calcium and magnesium are two chemical elements in the group 2 of the periodic table of elements. According to its atomic number, it locates in the group 2 and period 3 of the periodic table. This alkaline earth metal has atomic number 12 and element symbol Mg. This is the ninth most abundant chemical element on in the universe. Moreover, there are many other uses such as in the production of aluminium alloys, die-casting (alloyed with zinc), removing sulfur in the production of iron and steel, and the production of titanium in the Kroll process. we categorize it as an alkaline earth metal (all the group 2 elements are alkaline earth metals). 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. And, the electron configuration is [Ne] 3s2. (adsbygoogle = window.adsbygoogle || []).push({}); Copyright © 2010-2018 Difference Between. Calcium is a chemical element having the atomic number 20 and chemical symbol Ca. On the otherhand, the standard atomic weight of Mg is 24.305. 6. Therefore, it has 3 electron shells containing electrons. The most common oxidation state is +2, but it may form +1 oxidation state as well. although they are in the same group, they are in different periods of the periodic table because calcium has one extra electron shell than that of magnesium. Side by Side Comparison – Calcium vs Magnesium in Tabular Form The pure element is a silver-colored metal, but it tarnishes in air to give it a dull appearance. It also is an alkaline earth metal. It is an s block element, and it occurs as a solid at standard temperature and pressure. It has a hexagonal close-packed crystal structure. What is Magnesium Magnesium is a chemical element having the atomic number 12 and chemical symbol Mg. The key difference between calcium and magnesium is their appearance; calcium is a dull grey metal with a pale yellow tint whereas magnesium is a shiny grey metal. It is a shiny grey metal.

This chemical element occurs as sedimentary rocks such as limestone, mainly in two forms; calcite and aragonite. Available here, 1.”Calcium (20 Ca)”By Hi-Res Images ofChemical Elements (CC BY 3.0) via Commons Wikimedia   Magnesium is an essential macronutrient that plays a key role in many body processes, including muscle, nerve, and bone health, and mood. Whereas, magnesium is a chemical element having the atomic number 12 and chemical symbol Mg. Furthermore, the standard atomic weight of Ca is 40.078. In boiling water, the place of hydrogen is taken by Magnesium and a number of metals can be produced using thermal reduction of its salts and oxidized forms with magnesium. Terms of Use and Privacy Policy: Legal. It is in the group 2 and period 4 of the periodic table. Moreover, it is the fifth most abundant element in the earth’s crust. When it burns in air, magnesium produces a brilliant white light. The metal reacts with water to produce hydrogen gas. Magnesium react with oxygen at room temperature, forming a passivating layer of MgO on the surface. Magnesium metal dissolves readily in acids, even weak ones, forming Mg(II) ions and hydrogen, H, Magnesium react with oxygen at room temperature, forming a passivating layer of MgO on the surface. When considering the uses of this metal, the largest use is in steelmaking. All the elements in the group 2 are categorized as alkaline earth metals. Mg(II) is not precipitated by phosphate ions under acetic acid conditions. We find Magnesium in the second position in the periodic table. Crystals of pure magnesium metal. The atomic number of magnesium is 12 and its atomic mass is 24.305. When ingited, Mg reacts with both oxygen and nitrogen forming a mixture of magnesium oxide, MgO, and magnesium nitride, Mg 3 N 2. Magnesium is an element that is essential for human nutrition. Ammonia will also precipitate Mg(II) as hydroxide, but the precipitation is incomplete. the electron configuration of this element is [Ar] 4s2. It has an atomic mass of 24.305 and atomic number of 12. 2.”CSIRO ScienceImage 2893 Crystalised magnesium”By CSIRO, (CC BY 3.0) via Commons Wikimedia. Calcium and magnesium both are alkaline earth metal because both of them are in the group 2 of the periodic table of chemical elements.
