Question

(c) What is the energy of a photon of light, with a wavelength of 515 nm ? [2] (d) Use the Rydberg equation to explain the electron transition (or give \( \mathrm{n}_{1} \) and \( \mathrm{n}_{2} \) ) that leads to the emission of the spectral line mentioned in (c) assuming the emission is of a hydrogen atom. [2] (e) Copy the table below in your answer book and complete it for \( 3 / 4 \) of mark per correctly filled cell. Table 6: Abbreviated electron configuration and number of unpaired valence elements for given elements. \begin{tabular}{|c|l|l|} \hline Element & Electron configuration & Unpaired valence shell electrons \\ \hline Zn & & \\ \hline V & & \\ \hline Cr & & \\ \hline Mn & & \\ \hline \end{tabular}
