FAQs on Lecture 4: Problems on Hydrogen Atom Video Lecture - Quantum Mechanics for GATE - GATE Physics

1. What is the energy of the electron in the hydrogen atom?
Ans. The energy of the electron in the hydrogen atom can be calculated using the formula: E = -13.6 eV/n^2, where n is the principal quantum number.
2. How many quantum numbers are needed to describe the state of an electron in a hydrogen atom?
Ans. In order to describe the state of an electron in a hydrogen atom, three quantum numbers are needed: the principal quantum number (n), the azimuthal quantum number (l), and the magnetic quantum number (m).
3. What is the significance of the principal quantum number in the hydrogen atom?
Ans. The principal quantum number (n) in the hydrogen atom determines the energy levels of the electron. It also indicates the size and energy of the electron's orbital.
4. How does the quantum mechanical model of the hydrogen atom differ from the classical model?
Ans. The quantum mechanical model of the hydrogen atom considers the electron as existing in probability distributions around the nucleus, unlike the classical model which views the electron as orbiting the nucleus in fixed paths.
5. Can the hydrogen atom emit photons of any energy?
Ans. No, the hydrogen atom can only emit photons of specific energies corresponding to the energy differences between its discrete energy levels. This phenomenon is known as line spectra.
