Question

how is magnesium chloride formed by the transfer of electron why does the solution of magnesium chloride conduct electricity ​

Answer 1

Magnesium Chloride is formed by the transfer of electrons. They form an ionic bond. An ionic bond is a type of bond in which there is complete transfer of electrons from one atom to to other atom(s). The solution of Magnesium Chloride conducts electricity because it is electrolytic in nature.

Answer 2

Magnesium chloride conduct electricity only in molten form as it is a ionic compound and in molten form electrons are free to move.
