Considering the generic atomic orbital energy diagram; rank the three proposed electronic transitions-1s → 2s , 2s → 2p 34s-from lowest energy photon to highest energy photon required to induce the three proposed transitions. 9. 10. If an electronic transition from 4s3s results in emission of a "green" photon for a given elemental atom, then the electronic transition from 2s 1s would result in emission of a "red" or "blue" photon? 11.

Energy (eV) 1. The figure to the right shows the first few energy levels for lithium. The ground state for the valence electron (the electron most likely to change 4 energy levels) is the 2s state which is why that state is set to O eV. Make a table showing all possible transitions in the emission spectrum. For each possible transition indicate A. Energy change of possible transition. B. At for the transition. Is the transition allowed? C. Wavelength of...
1. in the mercury emission spectrum, three intense emission bands can be observed. in the Bohr model of the atom, each of these bands corresponds to a transition from a particular quantum orbital (energy level)n= 1,2,3 ..... for mercury, what color band corresponds to the largest energy difference between levels and which is the smallest? why is that? 2. is it possible for an atom to absorb a photon of red light and remit a photon of violet light? why?

1. According to experimental data, the electron affinities of C and N are -153.9 k.J/mol and -7 kJ/mol, respectively. Does this agree with the periodic trend for electron affinity? If not, explain why these values differ from the expected trend Hint: Look at the orbital diagrams for both atoms. What happens to each of the atoms? What configurations are the most stable?) 2.

When an electron of an excited hydrogen atom descends, from an initial energy level (ni) to a lower (nf), characteristic electromagnetic radiation is emitted. The Bohr model of the H-atom allows the calculation of ?E for any pair of energy levels. ?E is related to the wavelength (?) of the radiation according to Einstein's equation ( ?E = [(hc)/?]). Distinct series of spectral lines have been classified according to nf: Lyman series:nf=1 (91<?<123 nm; near-UV). Balmer series:nf=2 (365<?<658 nm; visible)....
