The Bohr model

Students often get confused between Rutherford’s model and Bohr model of an atom. They interpret the postulates of both these models to be the same, which is incorrect. Rutherford’s model differs from Bohr’s model in the following ways:

The ion Li2+ makes ail atomic transition from ail n = 4 state to ail n = 2 state, (a) What is the energy of the photon emitted during the transition? (b) What is the wavelength of the photon?
AI answered the problem this way. Is this correct? From the text you've provided, it seems like the problem at hand is to calculate the wavelength of a photon emitted when singly ionized helium (He+) transitions from the n=3n=3 to n=2n=2 state. Since He+ is a single-electron ion, it behaves like a hydrogen atom, so we can apply the same equations and principles. The text mentions the Balmer series, which corresponds to transitions to n=2n=2. The Balmer-alpha line, often referred to as the Hydrogen-alpha or Hα line, corresponds to the transition from n=3n=3 to n=2n=2 in hydrogen, and its wavelength is 656 nm. Since the helium ion (He+) behaves similarly to hydrogen in this context, the answer to the problem would also be 656 nm. The emitted photon has a wavelength of 656 nm.
