List of top Chemistry Questions on Bohr Model Of The Hydrogen Atom

The energy of the second bohr orbit of the hydrogen atom is $-328 \, \text{kJ mol}^{-1}$; hence the energy of the fourth bohr orbit would be:

The radius in the hydrogen atom in the ground state is $0.53$ \AA. The radius of $Li^{+2}$ ion (atomic number $= 3$) in a similar state is \ldots..

A spectral line of Lyman series of H-atom has a frequency of \(2.466 \times 10^{15} \, {s}^{-1}\). What is the transition responsible for this spectral line? (Rydberg constant \(R = 1.096 \times 10^7 \, {m}^{-1}\))

The total number of electrons with magnetic quantum number \(m_l = 0\) in Fe\(^{3+}\) and Cr\(^+\) is respectively

The radius of H atom in its ground state is \(x~\text{pm}\). What is the ratio of radii in ground and \(n = 2\) states of He\(^+\)?

Given that the radius of the first Bohr orbit of hydrogen atom is 53 pm, the radius of its third Bohr orbit is ................ pm. (Round off to the nearest integer)
