In the blockbuster film hit Back to the Future, which came out 30 years ago, and its sequels, this, 2015, is the future - the year Marty McFly and Doc Brown zoomed off to visit in their souped-up flying DeLorean.
Metallic bonding in magnesium. If you work through the same argument with magnesium, you end up with stronger bonds and so a higher melting point. Magnesium has the outer electronic structure 3s 2. Both of these electrons become delocalised, so the sea has twice the electron density as it does in sodium. The remaining ions also have twice the charge (if you are going to use this particular view of the metal bond) and so there will be more attraction between ions and sea.
Chemical and Physical Properties of Magnesium. 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.s mentioned in the chemical properties, magnesium is also present in many other compounds like dolomite, magnesium carbonate (that is also known as magnesite), and magnesium sulfate (which is also known by the name epsomite).
