NEET Physics Hydrogen Atom MCQ Question
Which combination of statements about the hydrogen atom is correct?
The ionisation energy of the hydrogen atom is 13.6 eV, the lowest energy state is n=1, and the electron transitions emit a photon.
The ground state of the hydrogen atom has maximum energy, the electron can only exist in n=0, and energy levels are continuous.
The spectrum of hydrogen shows continuous wavelengths, the electron can revolve in any orbit, and the energy is independent of n.
The ionisation energy is variable, the ground state is n=2, and angular momentum is not quantised.
Correct Answer
Detailed Explanation
The ionisation energy of the hydrogen atom is indeed 13.6 eV, the lowest energy state corresponds to n=1, and transitions of the electron between orbits do result in the emission of photons, confirming statement A.
