Question

Draw the electron dot structure of ${\mathrm{MgCl}}_2$.

Answer 1

Electron dot structure:-

1. These are basically the diagrams which are also known as Lewis structures.
2. These structures will show the bonding between the atoms of the molecule.
3. This will also show the lone pairs of electrons in a molecule.
4. Electron dot structure of ${\mathrm{MgCl}}_2$: As $\mathrm{Mg}$ has 2 valence electrons and it is metal too.
5. So, $\mathrm{Mg}$ will lose two electrons for the formation of ${\mathrm{Mg}}^{2+}$ion.
6. As $\mathrm{Cl}$ atom has 7 valence electrons and is a halogen, it will gain one electron from and form an ${\mathrm{Cl}}^{-}$ion.
7. So, two $\mathrm{Cl}$ atoms would be required for the complete formation of ${\mathrm{MgCl}}_2$.
