There are many famous kinds of metallic alloys. Formation of Alloy with Metallic BondingĮlements can occur as metallic, but they can also combine with each other, and virtually any combination of two metallic elements forms an alloy, which also displays the properties of metals. Metal ion bonding series#This is a transcript from the video series The Joy of Science. And, indeed, it turns out that about three-quarters of all the elements in the periodic table are metals. Those are all elements that want to give up electrons. If you look at the periodic table, almost all the elements that are on the left side of the diagram are metals. Metallic bonding in nature is extremely common. The negative sea holds the positive charges together, and that’s how metallic bonding works. The sodium atoms themselves dispersed around that negative sea. And they form a sea of a negative charge, of free-floating electrons.Īnd in that sea, there are positive centers. So when a bunch of sodium atoms comes together, that’s exactly what they do-they all give up electrons. Think about a large collection of sodium atoms-that’s element 11- and every one of those atoms wants to get rid of an electron.

Meanwhile, covalent bonding involves sharing of electrons, like metallic bonding, but in this case only locally with a few atoms. This behavior is distinctive from ionic bonds wherein one atom takes an electron, and the other one gives it away. In metallic bonding, atoms adopt the strategy of sharing electrons. , George Mason University There are two different types of chemical bondings: metallic and covalent.
