Ques:- Two elwment A&B are such that the bond energy of A-A molecule &B-B molecule & A-B molecule are 81, 64 and 76 respectively. If E.N. of atom A is 2.4 than find out the E.N. of atom A in mulliken Scale.
Ans:- delta = 76-√81*64
= 76-9*8 = 4
Xa-Xb = 0.208√4
= 0.208*2
= 0.416
Xa-2.4 = 0.416
Xa= 0.416+2.4
= 2.816
2.816 = E.A+I.P/2*2.8
7.3 = E.A +I. P/2
X(mulliken)= 7.3
