5.ane.ii - Ionic Bonding in Magnesium Chloride

There are many compounds which accept ionic bonds. They are called ionic compounds, and they are formed when metals react with nonmetals. In section 5.1.one nosotros saw an case of an ionic compound.

Allow's examine another ionic chemical compound, 1 that doesn't have a 1:1 metallic ion to nonmetal ion ratio. We'll use Lewis Electron Dot Symbols to describe the ionic bonding that is observed in magnesium chloride. The germination of magnesium chloride can be thought of as a event from a reaction involving magnesium metal, Mg and chlorine gas, Cl_two. The reaction tin can be thought of involving the following simultaneous processes:

The Oxidation of Magnesium Metal
Call up from section four.6, a magnesium atom loses its 2 outer-shell electron to become a magnesium ion, (i.due east. cation). The magnesium metallic is said to exist oxidized.
The Reduction of Chlorine Gas
Call back from section 4.seven, chlorine is a diatomic element. The covalently bonded Cl_two molecule gains 2 electrons to become two chloride ions, (i.e. anions). Chlorine is said to be reduced.

Combining the above oxidation and reduction processess, the overall outcome is the transfer of 2 electrons from magnesium to chlorine.

The oppositely charged of the magnesium and chloride ions concenter each other and ionic bonds are formed. In the solid country, each cation is surrounded by anions, and each anion is surrounded past cations. The simplest ratio of Mg⁺² : Cl^- is 1:2. The simplest formula for this ionic compound is MgCl₂ .
