Magnesium gets its name from the district of Magnesia in Greece where the compound magnesium carbonate was first found. Thus, we can conclude that out of the given options alkaline earth metals are found on the periodic table in group 2. 0. The periodic table, also known as the periodic table of elements, arranges the chemical elements such as hydrogen, silicon, iron, and uranium according to their recurring properties.

On the periodic table of the elements, atomic radius tends to increase when moving down columns, but decrease when moving across rows (left to right). For many years magnesium was thought to be the same element as calcium. It would be Ne = NEON. The two most important sources are natural minerals like Dolomite and Magnesite. 1. A magnesium fire is very difficult to put out as it can … Magnesium is the chemical element of the periodic table of the elements which has as symbol Mg and as atomic number 12.Magnesium is the eighth most abundant element and constitutes about 2% of the earth's crust; it is also the third for abundance among the elements dissolved in sea water. Answers (1) Chosposi 1 February, 08:11. The number of each element corresponds to the number of protons in its nucleus (which is the same as the number of electrons orbiting that nucleus). Magnesium is a chemical element with the symbol Mg and atomic number 12. The elements in the second group of the periodic table are called alkaline earth metals and they have two electrons in their outermost orbital. Magnesium is an element in the second group of periodic table with atomic number 12 and it is in the third period of the periodic table. Not Sure About the Answer? Answer. Magnesium is the 12 th element on the Periodic Table, the lightest among the metals for structural application. Chemistry. Troyes 1 February, 06:37. New questions in Chemistry . The density of magnesium is 1.738 grams per cubic centimeter. Interesting Facts about Magnesium. It is a shiny gray solid which bears a close physical resemblance to the other five elements in the second column (group 2, or alkaline earth metals) of the periodic table: all group 2 elements have the same electron configuration in the outer electron shell and a similar crystal structure. The atomic number of magnesium is 12 and its atomic mass is 24.305. It’s necessary to apply a process to retrieve a usable amount of Mg. Magnesium is not found in a pure form because it bonds with other elements. Magnesium can easily be molded, shaped, bend and cut and can be turned into various useful products in ways other metals cannot be used. Elements of this group are beryllium, magnesium, calcium, strontium, barium and radium. Magnesium belongs to the Group 2 (IIA) of periodic tables which makes it one of the alkaline earth elements. Isotopes Magnesium has three stable isotopes including magnesium-24, magnesium-25, and magnesium-26. Consequently, the smallest atom is helium with a radius of 32 pm, while one of the largest is caesium at 225 pm.
