Question

Explain the ionic bond formation between magnesium and chlorine?

Answer 1

Hint: An ionic bond is a chemical bond formed by the transfer of electrons from one atom to another. When one atom can contribute electrons to achieve the inert gas electron configuration and the other atom requires electrons to achieve the inert gas electron configuration, an ionic bond is formed.

Complete answer:
As $Mg$ has a valency of $ + 2$ and chlorine has a valency of $ - 1$, $MgC{l_2}$ is formed through the transfer of electrons.
Magnesium chloride is formed by a reaction between magnesium metal, $Mg$ , and chlorine gas, $C{l_2}$ .To form a magnesium ion, a magnesium atom, which is a Group \[II{\text{ }}A\] metal, tends to shed its two outer-shell valence electrons (i.e. cation). It is said that the magnesium metal has oxidized.
Two electrons are gained by the covalently bound $C{l_2}$ molecule, resulting in two chloride ions (i.e. anions). Chlorine concentrations are said to be lower. The two electrons that the magnesium atom loses are acquired by the chlorine atom, resulting in the formation of a magnesium ion and two chloride ions.
Ionic bonds are formed when the oppositely charged magnesium and chloride ions attract one another. Each cation has anions surrounding it, and each anion has cations surrounding it. $MgC{l_2}$ is the simplest formula for this ionic molecule.

Note:
Ionic bonds are the most powerful of all bonds. The ionic bond is the most reactive of all the bonds in the proper medium since it contains charge separation. The melting and boiling points of ionic compounds are quite high.
