AIPMT PRELIMS 2010 Physics Energy Levels MCQ Question
Type: MCQ-conceptual-Medium-Class 12
The energy of a hydrogen atom in the ground state is −13.6 eV. The energy of a He⁺ ion in the first excited state will be
A
−6.8 eV
B
−13.6 eV
C
−27.2 eV
D
−54.4 eV
Correct Answer
Option B
Detailed Explanation
The energy of a He⁺ ion in the first excited state is given by Eₙ = Z²/n²(−13.6 eV). For He⁺, Z = 2 and n = 2, so Eₙ = −13.6 eV.
