Question

Second excitation potential for He+ ion is (1) 12.09 eV (2) 48.36 eV (3) 3.4 eV (4) 51 eV

Answer 1

Answer:

12.09 eV

Explanation:

Exitation potential =  13.6  (  1/n1^2  -  1/n^2)

     13.6 ( 1- 1/9 )    

 (   for second excitation potential for He+ {it is similar to H in having only 1                       electron} electron is exited from n1=1 to n2= 3)

 that is exitation potential.

E =  13.6 * 8

           9

E= 12.09 eV.
