Identify the incorrect statement from the following.

If radius of second Bohr orbit of the ${\mathrm{He}}^{+}$ ion is $105.8 \mathrm{pm}$, what is the radius of third Bohr orbit of ${\mathrm{Li}}^{2+}$ ion?

A particular station of All India Radio, New Delhi, broadcasts on a frequency of $1,368 \mathrm{kHz}$ (kilo Hertz). The wavelength of the electromagnetic radiation emitted by the transmitter is [speed of light, $\mathrm{c}=3.0\times {10}^8{ \mathrm{ms}}^{-1}$]

The number of angular nodes and radial nodes in $3\mathrm{s}$ orbital are

$4\mathrm{d},\mathrm{ }5\mathrm{p},\mathrm{ }5\mathrm{f}$ and $6\mathrm{p}$ orbitals are arranged in the order of decreasing energy. The correct option is:

Which of the following series of transitions in the spectrum of hydrogen atom falls in visible region?

What is the maximum number of orbitals that can be identified with the following quantum number $\mathrm{n}=3,\mathrm{ }\mathrm{l}=1,\mathrm{ }\mathrm{m}=0$?

Calculate the energy in corresponding to light of wavelength $45\mathrm{ }\mathrm{n}\mathrm{m}:$ (Planck’s constant $\mathrm{h}=6.63\times {10}^{-34}\mathrm{J}\mathrm{s}:\mathrm{s}\mathrm{p}\mathrm{e}\mathrm{e}\mathrm{d}\mathrm{ }\mathrm{o}\mathrm{f}\mathrm{ }\mathrm{l}\mathrm{i}\mathrm{g}\mathrm{h}\mathrm{t}\mathrm{ }\mathrm{c}=3\times {10}^8 \mathrm{m}{\mathrm{s}}^{-1})$
