The Lyman series results from transitions of the electron in hydrogen in which the electron ends at the n = 1 energy level. Using the Rydberg formula for the Lyman series, calculate the wavelength 2-1 of the photon emitted in the transition from the n = 2 energy state. Give an answer in units of nanometers (nm). 12-1 = Identify the band of radiation from the electromagnetic spectrum to which the 12-1 photon belongs. infrared visible light ultraviolet X-ray Using the Rydberg formula for the Lyman series, calculate the wavelength 24-1 of the photon emitted in the transition from the n = 4 energy state. Give an answer in units of nanometers (nm). 24-1 = Identify the band of radiation from the electromagnetic spectrum to which the 14-1 photon belongs. nm nm

PROVISIONAL LEWIS STRUCTURES T01/S01 For each provisional structure, identify if it is the correct Lewis structure (C) or if it needs to be modified according to procedure MA or MB to obtain the correct Lewis structure. MA. Form multiple bonds to the central atom using lone pair on the terminal atom(s) until the central atom has an octet (or septet). MB. Form multiple bonds to the central atom using lone pair on the terminal atom(s) until the central atom has a formal charge of zero (0) or until two double bonds are formed. A provisional structure has the valence electrons distributed in order as (1) a bond between each pair of atoms, (2) an octet for each ligand (terminal) atom or ligand group (CH3, NH2 or OH) and (3) any remaining electrons on the central atom.
