NEET Physics Hydrogen Atom MCQ Question
Type: MCQ-conceptual-Medium-Class 12
Which of the following statements about the hydrogen atom is correct?
A
The ground state energy of hydrogen is -13.6 eV, and this is the lowest energy level for the electron.
B
An electron in a hydrogen atom can have any energy above 0 eV without being ionized.
C
The ionization energy for hydrogen is 10.2 eV, which is the energy needed to free the electron.
D
In hydrogen, the electron spends most of its time in the second energy level at room temperature.
Correct Answer
Option A
Detailed Explanation
The ground state energy of the hydrogen atom is indeed -13.6 eV, which represents the lowest energy level for the electron. This is supported by the statement that the minimum energy required to free the electron from the ground state is 13.6 eV.
