The answer is the excited state of the hydrogen atom, n=24 and Z=23

Kinetic energy of electron is, $\mathrm{KE}=\frac{13.6 \mathrm{Z}^{2}}{\mathrm{n}^{2}} \mathrm{eV}$

For the excited state of the hydrogen atom , n=24 and Z=23

K.E= $\frac{13.6 \times 23^{2}}{24^{2}}=$ 12.5

What is the hydrogen atom?

The hydrogen atom is the most basic of all the atoms since it just has one proton and one electron.
There are two more hydrogen isotopes, deuterium and tritium, in addition to protium, which is the most prevalent form of the atom.
The hydrogen atom consists of a proton and an electron, and has a spherical symmetry that can most easily be studied using a spherical polar coordinate frame.

The correct answer to the question is 8.33 minutes.

CALCULATION:

The distance of earth from sun s = 150 million km.

We know one million = 10 lakh = $10^6$
