State Bohr's postulates and derive an expression for the energy of electron in nth orbit in Bohr's model of hydrogen atom.
Calculate binding energy per nucleon (in MeV) of ¹²₆C. Given : m(¹²₆C) = 12.000000 u, m(¹₀n) = 1.008665 u, m(¹₁H) = 1.007825 u
State Bohr's postulate to explain stable orbits in a hydrogen atom. Prove that the speed with which the electron revolves in nth orbit is proportional to (1/n).
How did de Broglie hypothesis provide an explanation for Bohr's second postulate for quantisation of orbital angular momentum of the orbiting electron in hydrogen atom ? Discuss.
Identify the transition of electron in Bohr model which gives rise to (i) the maximum, and (ii) the minimum wavelength in Balmer series of hydrogen spectrum.
The ratio of the magnitude of magnetic moment to that of angular momentum, of an electron revolving around the nucleus in a hydrogen atom is :
