See below.

Explanation:

${MgCl}_{2}$ $"MgCl"_2$ is an ionic compound.

The electron configuration of $Mg$ $"Mg"$ is $1 s^{2} 2 s^{2} 2 p^{6} 3 s^{2} 3 p^{6} 4 s^{2}$ $1s^2 2s^2 2p^6 3s^2 3p^6 4s^2$ .

$Mg$ $"Mg"$ can get a noble gas $s^{2} p^{6}$ $s^2p^6$ configuration by losing its two $4 s$ $4s$ electrons and forming a magnesium ion, ${Mg}^{2 +}$ $"Mg"^(2+)$ .

The electron configuration of $Cl$ $"Cl"$ is $1 s^{2} 2 s^{2} 2 p^{6} 3 s^{2} 3 p^{5}$ $1s^2 2s^2 2p^6 3s^2 3p^5$ .

$Cl$ $"Cl"$ can get a noble gas $s^{2} p^{6}$ $s^2p^6$ configuration by gaining an electron and forming a chloride ion, ${Cl}^{-}$ $"Cl"^"-"$ .

The Lewis structure of ${MgCl}_{2}$ $"MgCl"_2$ is therefore

Lewis structure
(From www.superteachertools.net)

The compound is held together by electrostatic attractions between the positively charged magnesium ion and the negatively charged chloride ions.
