To determine whether the wavelength released when an electron drops from n = 4 to n = 2 in Li²⁺ lies in the visible region, we can follow these steps: ### Step 1: Identify the transition The electron is transitioning from a higher energy level (n = 4) to a lower energy level (n = 2). ### Step 2: Use the Rydberg formula We will use the Rydberg formula for hydrogen-like atoms to calculate the wavelength of the emitted photon: \[ ...
