Calculate %ic of the interatomic bonds for the intermetallic compound al6mn.

We need to know the electronegatives of the elements in the compound which are Al and Mn as the %ic is an electronegative function.

Electronegative of Al is 1.5

Electronegative of Mn is 1.6

%ic = [1 - exp (-0.25) (1.6 - 1.5) ^2] x 100

%ic = [1 - exp (-0.25) (0.01) ] x 100

%ic = 0.25%
