Question

a. Show the formation of magnesium chloride and sodium chloride by the
transfer of electrons.

b. Identify the ions present in these compounds.

c. Why do ionic compounds not conduct electricity in the solid state?​

Answer 1

Explanation:

R.E.F image 

Mg12=1s22s22p63s2

Cl17=1s22s22p63s23p5

⇒Mg2+[Cl−]2⇒MgCl2 is formed 

MgCl is an ionic compound formed by the transfer  

of electrons from electron rich to electron deficient 

species 

In molten or dissolved state ionic compounds conduct 

electricity because they contain charged particle called 

cations and anions These ions are free to move and 

conduct electricity.

Answer 2

$\underline{\underline{ \sf \huge \red{Answer :-}}}$

• Mg forms ionic bond to Cl by donating its valence electrons to two Cl atoms. The electron configuration of Mg is [Ne]3s². It can achieve a complete octet by losing its two valence electrons to form Mg²⁺. The electron configuration of Cl is [Ne]3s²3p⁵.

• Magnesium chloride. An inorganic compound consisting of one magnesium and two chloride ions. The compound is used in medicine as a source of magnesium ions, which are essential for many cellular activities. It has also been used as a cathartic and in alloys.
