Question
1st excitation potential for the H-like (hypothetical) sample is 24 V. Then :
Options
A.Ionisation energy of the sample is 36 eV
B.Ionisation energy of the sample is 32 eV
C.Binding energy of 3rd excited state is 2 eV
D.2nd excitation potential of the sample is 
V
VSolution
1st excitation potential = 10.2 Z2 = 24 V ∴ Z2 = 24/10.2
∴ IE = 13.6 Z2 =
= 32 eV.
Binding energy of 3rd excited state = 0.85 Z2 =
= 2eV.
2nd excitation potential of sample = 12.09 Z2 =
V.
∴ IE = 13.6 Z2 =
= 32 eV.Binding energy of 3rd excited state = 0.85 Z2 =
= 2eV.2nd excitation potential of sample = 12.09 Z2 =
V.Create a free account to view solution
