- A (a) , (b)
- B (a) , (b)
- C (a) , (b)
- D (a) , (b)
Answer & Solution
Correct Answer
(B) (a) , (b)
Step-by-step Solution
Detailed explanation
(a) For Hydrogen atom, For ground state, n=1, energy is E1=-13.612=-13.6 eV For second excited state, n=3, Energy is E2=-13.632=-1.5 eV Energy required is ∆E=E2-E1=-1.5+13.6=12.1 eV≈12 eV (b) lonization energy is defined for ground state only, so…
