Question
**Title: Calculating the Energy of Electron Excitation** **Question 4:** Determine the energy (in Joules) associated with an electron being excited from \( n = 2 \) to \( n = 7 \). Provide your answer to three significant figures and in exponential format (e.g., 1.23E-3). Do not include the units in the answer. \[ E = -B \left[ \left( \frac{1}{n_f^2} \right) - \left( \frac{1}{n_i^2} \right) \right] \] Where: - \( B = 2.18 \times 10^{-18} \) J ### Explanation: This formula is used to calculate the energy change when an electron transitions between two energy levels in an atom. Here, \( n_i \) represents the initial energy level, and \( n_f \) is the final energy level. The variable \( B \) is a constant representing the energy of one photon in joules.
