The ionization potential of hydrogen atom is . How much energy need to be supplied to ionize the hydrogen atom in the first excited state.
- A
- B
- C
- D
Answer & Solution
Correct Answer
(C)
Step-by-step Solution
Detailed explanation
Ionization energy is the minimum amount of energy required to remove the most loosely bound electron of an isolated neutral gaseous atom or molecule. Energy of an orbit is inversely proportional to the square of principal quantum number, E∝1n2 ⇒E2E1=n12n22…
