Chemistry - Atomic Structure Question with Solution | TestHub

The radius of the $2^{\mathrm{nd}}$ orbit of ${\mathrm{He}}^{+}$ is equal to the radius of the $1^{\mathrm{st}}$ orbit of H-atom

The speed of the electron in the $2^{\mathrm{nd}}$ orbit of ${\mathrm{He}}^{+}$ is equal to the speed of the electron in the $1^{\mathrm{st}}$ orbit of H-atom

The shortest wavelength in Pfund series of H-atom is 16/RH

The frequency of revolution of an electron in $n^{\mathrm{th}}$ orbit of H-like species is directly proportional to $n^2$
