Discussion Quiz #7 (10 pt) CHM 113 AA/AB Name:_____KEY___________________ Section:_________________________ 1. (2pt) Describe each process below. a. Absorption Excitation of an electron to a higher state b. Relaxation of an electron to lower state. emission 2.(2 pt) Draw a node diagram for a 2s orbital. Not worried about distance, just shape (smaller first part, node and larger second hump) 3.(2 pt) What is the frequency of light with energy of 5.87 x 10-19 J? E=h 5.87 x 10-19 J=(6.626 x 10-34 J*s) =8.86 x 1014 s-1 4. (3 pt) Write the electron configuration for Ca2+ and draw an electron box diagram for that ion. 18 e-, 1s2, 2s2, 2p6, 3s2, 3p6 Box diagram should show one up and one down electron each box--and p orbitals have 3 boxes while s orbitals have 1 5. (1pt) Will wavelength selection affect the % transmittance of the colored solution? Why or why not? Yes, the percent transmittance depends on the wavelength of light and the color of the solution .
