To remove an electron from the first orbit to infinity of hydrogen atom, the amount of energy required will be :
- A - 13.6 eV
- B 13.6 eV
- C -3.4 eV
- D 3.4 eV
Answer & Solution
Correct Answer
(B) 13.6 eV
Step-by-step Solution
Detailed explanation
Energy required: \( \Delta E = E_{\infty} - E_1 = 0 - \left( \frac{-13.6}{1^2} \right) \text{ eV} = 13.6 \text{ eV} \)
