Question

How is Magnesium Chloride formed by the transfer of electrons? Why does the solution of Magnesium chloride conduct electricity?

Answer 1

the valence electrons in Magnesium is 2 where as the valence electron in the chlorine is one therefore by the cross multiplication we have the product is MgCl2

MgCl2 is a ionic compound therefore it is a good conductor of electricity because of the free electrons present in this compound

Answer 2

Formation of Magnesium chloride:

In order to achieve a complete octate,, magnesium has to lose its two valence electrons similarly, for chlorine to achieve its octate, it has to gain one electron, which is why magnesium combines with chlorine by donating its two valence electrons and forms an ionic bond. Chlorine receives these two valence electrons and forms one magnesium and 2 chloride ions

Mg + Cl-- MgCL2

Conduction of electricity:

Magnesium chloride only conducts electricity when in molten or liquid state. It is an ionic compound and in liquid state it releases its ions when enables them to conduct electricity.
