List of top Physics Questions on Atomic Structure asked in UP Board XII

Describe briefly Rutherford's \(\alpha\)-particle scattering experiment. What are the shortcomings of this model? How are they rectified in Bohr's model?
If the circumference of the nth orbit of an electron is \(S\) and the corresponding de Broglie wavelength of the orbit is \(\lambda\), then on the basis of Bohr's atom model, prove that \(S = n\lambda\).
In hydrogen atom, the kinetic energy of electron in an orbit of radius \( r \), is given by:
Draw energy level diagram for hydrogen atom. Show the transitions of the first line of Lyman series and second line of Balmer series. Find out the ratio of their wavelengths.
Hydrogen atom in its ground energy state absorbs a photon, which excites it to an energy level of \(n = 4\). Calculate the frequency of photon.
Mention the most important conclusion of Rutherford's alpha-particle scattering experiment. Define isotopic, isobaric, and isotonic nuclei. Find the energy equivalent to one atomic mass unit in joules and MeV (1 u = 1.6605 × \(10^{-27}\) kg).
What is the meaning of stationary orbit of atom? Deriving formula for the energy of the electron in the stationary orbit of the hydrogen atom, mention its relation with the radius of the orbit of electron.
Energy of electron in the \(n\)th orbit of hydrogen atom is \( E_n = \frac{-13.6}{n^2} \, \text{eV} \). Draw the energy level diagram for hydrogen atom and show the transition for lines of Balmer and Paschen series.
Mention the major drawbacks of Rutherford's atomic model.
