Expert Solution

Explanation of Solution

For Li2+ atom,

Value of Z is 3.

Value of n is 1.

Substitute the values in above equation.

E=−2.178×10−18 J(Z2n2)=−2.178×10−18 J((3)2(1)2)=−19.602×10−18 J

This energy is to be converted into kJ/mol as follows:

E=(−19.602×10−18 J)(10−3 kJ1 J)(6.023×1023)=−11806.2846 kJ/mol
