ANSWER

ΔE=13.6 eV(1nf21ni2)\Delta E=13.6\ \text{eV}\left(\frac{1}{n_f^2}-\frac{1}{n_i^2}\right). Energy difference between levels determines photon energy in transitions, positive for emission when ni>nfn_i>n_f.

Practice questions

1 of 50Practice questions for this set
A researcher studies a one-electron atom that emits a line spectrum similar to hydrogen. When the nucleus is replaced with a different isotope (same atomic number, different mass), the bright emission lines are observed at essentially the same wavelengths within the instrument's resolution. Which statement best accounts for this result using the principle of quantized energy levels?
