1. The problem statement, all variables and given/known data In a hot star, a multiply ionized atom with a single remaining electron produces a series of spectral lines as described by the Bohr model. The series corresponds to electronic transitions that terminate in the same final state. The longest and shortest wavelengths of the series are 63.3 nm and 22.8 nm, respectively. a.) What is the ion? b.) Find the wavelengths of the next three spectral lines nearest to the line of longest wavelength. 2. Relevant equations En = -13.6 Z2/n2 1/ [tex]\lambda[/tex] = R((1/nf2) - (1/no2)) 3. The attempt at a solution To be honest, I'm not even sure where to start. I did try finding nf for the shortest wavelength assuming that the electron started at n = infinity, but it gave a decimal value. The only other thing I can think of is somehow assuming the n in the first equation and the nf in the second are equivalent.
