Question

How is Magnesium Chloride formed by the transfer of electrons? Why does the solution of Magnesium chloride conduct electricity? 2

Answer 1

Hello,

In this process, magnesium is an electron donator and chlorine act as electron receiver. Actually, magnesium has to lose its two electrons and chlorine has to gain one electron to achieve their complete octate. Then ionic bond formation takes place between Mg and Cl ions which gives magnesium chloride as resulting compound.

Why magnesium chloride conduct electricity :

Magnesium chloride is an ionic compound. Magnesium chloride release ions in the solution which actually conduct electricity.

Hope it helped

Answer 2

Explanation:

• The atomic number of magnesium is 12 and electronic configuration is $1 \mathrm{s}^{2} 2 \mathrm{s}^{2} 2 \mathrm{p}^{6} 3 \mathrm{s}^{2}.$

• The atomic number of chlorine is 17 and electronic configuration is$1 \mathrm{s}^{2} 2 \mathrm{s}^{2} 2 \mathrm{p}^{6} 3 \mathrm{s}^{2} 3 \mathrm{p}^{5}.$

• The valence of magnesium is $\mathrm{Mg}^{2+}$ and chlorine.
• Magnesium donates two electrons to two chlorine atom to get stable octet electronic configuration as well chlorine also get stable octet electronic configuration by accepting of one electron. And form $\mathrm{MgCl}_{2}.$

• Magnesium chloride dissolved in water and dissociated into its ions they are $\mathrm{Mg}^{2+}$ and $\mathrm{Cl}^{-}$these ions are conduct electricity.

• Hence, magnesium chloride solution conducts electricity.
