Answer 2

Answer:

Explanation:

Magnesium is a metal and Chlorine is a non-metal, so when magnesium and Chlorine react to form Magnesium Chloride (MgCl2), they do so by transfer of electron and form an ionic compound.

Now, Atomic Number of Magnesium is 12 and that of Chlorine is 17.

The number of electrons in K L M shells; in Magnesium are 2, 8,2 and, in Chlorine are 2, 8, 7.

So, Mg loses two electrons from its outermost shell M now, Mg has 10 electrons in its shell (2, 8) and becomes positively charged ion. The two electrons lost by Mg are gained by two Chlorine atoms, in outermost shell M, so Chlorine atoms now have 18 electrons each in shell (2, 8, 8) and becomes negatively charged ion.

In Magnesium Chloride, Two Chloride ions are attracted to one sodium ion due to opposite charges on them and they exist as cluster of oppositely charged ions.
