An electron in a hydrogen atom is excited from the ground state to the n = 4 state. The wavelength of light emitted when the electron drops from n = 4 to n = 1 is longer than that from n = 4 to n = 2, statement is true and which are false?

A photon has a wavelength of 624 nm. Calculate the energy of the photon in joules.

An electron in the hydrogen atom makes a transition from an energy state of principal quantum number $n_1$ to the n = 2 states. If the photon emitted has a wave length of 434 nm, what is the value of $n_1$?

The ionization energy is the energy required to completely remove an electron from the ground state of an atom or ion. Calculate the ionization energies (in KJ $mol^{-1} )$ of the $He^+$ and $Li^{2+}$ ions.
