Suppose that a hypothetical atom gives a red, green, blue and violet line spectrum, which jump according to the figure would give off the red spectral line?

Which of the following is electronic configuration of ${\mathrm{Cu}}^{2+}(\mathrm{Z}=29)$ ?

In a sample of $\mathrm{H}-$atom, electrons make transition from $5^{\text{th }}$ excited state to ground state, producing all possible types of photons, then number of lines in infrared region are:

The energy of a photon of wavelength $\mathrm{\lambda }=1$ meter is: (Planck's constant $=6.626\times {10}^{-34} \mathrm{J}.\mathrm{s}$, speed of light $=3\times {10}^8{\mathrm{ms}}^{-1}$)

The set of principal $\left(\mathrm{n}\right)$. azimuthal $\left(\mathrm{l}\right)$ and magnetic $\left({\mathrm{m}}_1\right)$ quantum numbers that are not allowed for the electron in $\mathrm{H}-$atom is:

The electron in hydrogen atom is in the first Bohr orbit $\left(\mathrm{n}=1\right)$. The ratio of transition energies, $\mathrm{E}\left(\mathrm{n}=1\to \mathrm{n}=3\right)$ to $\mathrm{E}\left(\mathrm{n}=1\to \mathrm{n}=2\right)$, is:

The maximum number of electrons that can be filled in the shell with the principal quantum number $\mathrm{n}=3$ is:

For a $4\mathrm{p}$ orbital, the number of radial and angular nodes, respectively, are:
