An atomic transition 1D → 1P in a magnetic field of 2 T shows Zeeman splitting. Given that the Bohr magneton μB = 1.53 × 10-24 J/T and the wavelength corresponding to the transition is 650 nm, the separation in the Zeeman spectral lines is approximately:

In the standard chemical symbol representation of an element, AZM, what do A and Z represent respectively?

Which theory did Niels Bohr challenge to explain line spectra of atoms?

According to the Bohr model, the energy of the emitted photon due to a transition from the 3rd excited state to the ground state in a hydrogen atom is:
