Question

Calculate the ionic character (in percent) of the interatomic bonds for the following materials: (a) CaCl2

Answer 1

Answer – We know the ionic character of the interatomic bonds is depending on the electronegativity difference between the two atoms. We know, when electronegativity difference more than 1.7 then there is ionic bond characterized.

So when the electronegativity difference is 1.7 then there is ionic character is 50 %

For the CaCl₂ the electronegativity difference = 3.16 -1 = 2.16

So, at 1.7 = 50 %

So, 2.16 = ?

= 63.5 %

the ionic character (in percent) of the interatomic bonds for CaCl₂ is 63.5 %
