Part awhat is the change in energy ? e of the hydrogen atom as the electron makes the transition from the n=3 energy level to the n=1 energy level? express your answer numerically in electron volts. part bwhen an atom makes a transition from a higher energy level to a lower one, a photon is released. what is the wavelength of the photon that is emitted from the atom during the transition from n=3 to n=1? express your answer numerically in angstroms. part cwhen the hydrogen atom makes the transition from the n=2 to the n=1 energy level, it emits a photon. this photon can be absorbed by to a singly ionized helium atom (he+) in its second energy level (ninitial=2), causing it to move to a higher energy level. to what final energy level number nfinal can the photon promote the helium ion? note that he+ has two protons in its nucleus and a single electron. express your answer as an integer.
