Ionisation energy of hydrogen atom is ground state is 13.6 eV. The energy released (in eV) for third member of Balmer series is
(a)13.056
(b)2.856
(c)0.967
(d)0.306
Answer
Answer: B ✓ checked by 4AB · confidence high
Explanation
Third Balmer line is n = 5 → 2: ΔE = 13.6(1/4 − 1/25) = 13.6 × 0.21 = 2.856 eV.
