List of top Chemistry Questions on Bohr Model Of The Hydrogen Atom asked in AP EAPCET

In hydrogen spectrum, the frequency of the spectral line corresponding to electron transition $n_2 = 3$ to $n_1 = 2$ is $x$ Hz. What is the frequency (in Hz) of the spectral line corresponding to electron transition $n_2 = 4$ to $n_1 = 3$ of $\text{He}^+$ spectrum?

If the energy required to remove an electron from the ground state of \(He^+\) is \(x\) J, the energy (in J) required to remove an electron from the ground state of \(Li^{2+}\) is:

Wavelength of a particular line in Balmer series of atomic spectrum of hydrogen is 656.4 nm. What is the wavelength (in nm) of corresponding line in the spectrum of $He^{+1}$?

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..

The radius of the first orbit of \(Li^{2+}\) is \(X\ \text{\AA}\). The radius of the third orbit of \(He^{+}\) (in ) is

The velocity of the electron in Bohr's first orbit is \(x\times10^6\ \text{m s}^{-1}\). The de Broglie wavelength associated with it (in nm) is
