The energy required to remove an electron from the $n = 10$ state of a hydrogen atom is ....... (in $, eV$)

The energy levels of a hydrogen atom are shown below. The transition corresponding to the emission of the shortest wavelength is

In the Bohr model of the hydrogen atom,the lowest orbit corresponds to:

Energy of an electron in the second orbit of a hydrogen atom is $E_{2}$. The energy of an electron in the third orbit of $He^{+}$ will be

In a hydrogen atom,if the difference in the energy of the electron in $n = 2$ and $n = 3$ orbits is $E,$ the ionization energy of the hydrogen atom is ....... $E$.

An electron collides elastically with an $H$-like atom and excites it from the ground state to $n = 3$. Find the energy transferred to the $H$-like atom in $eV$.
