According to Bohr's theory of Hydrogen atom, only those atomic orbits with radil "P" and atomic shell "n" around the nucleus are allowed which have the angular momenta:
Correct answer: A. nh/2π
- A. nh/2π
- B. n^2h/2π
- C. h/2π
- D. n^3h/2π
Explanation
This is the correct answer. According to Bohr's theory, the angular momentum of an electron in a hydrogen atom is quantized and can only take on discrete values. The allowed values of angular momentum are given by L = nh/2π, where n is the principal quantum number (which determines the energy level of the electron), and h is Planck's constant.

About Atomic Structure
Atomic structure covers the discovery of the proton, Planck's quantum theory, hydrogen emission spectra and the evidence for quantized energy levels. You will use quantum numbers to describe orbitals, distinguish s, p, d and f orbital shapes, and write electronic configurations, including the correct order of electron filling.
