List of top Physics Questions on Atomic Structure asked in IIT JAM PH

Let $T_g$ and $T_e$ be the kinetic energies of the electron in the ground and the third excited states of a hydrogen atom. According to the Bohr model, the ratio $T_g/T_e$ is
KC1 has the NaCl type structure which is fcc with two-atom basis, one at \( (0, 0, 0) \) and the other at \( \left( \frac{1}{2}, \frac{1}{2}, \frac{1}{2} \right) \). Assume that the atomic form factors of \( K^+ \) and \( Cl^- \) are identical. In an x-ray diffraction experiment on KC1, which of the following \( (h k l) \) peaks will be observed?
Consider Rydberg (hydrogen-like) atoms in a highly excited state with \( n \) around 300. The wavelength of radiation coming out of these atoms for transitions to the adjacent states lies in the range:
