2)
What is the energy of light with a frequency of 4.51 x 106 Hz? h = 6.626 x
10-34 J sec, c = 3.00 x 108 m/sec.
E = hv = (6.626 x 10-34 J s)(4.51 x 106 /s) = 2.99 x 10-27 J

7)
What are the allowable quantum numbers for an electron in the third
energy level?
n=3
l = 0, 1, 2
ml = -2, -1, 0, 1, 2
ms = -1/2, + 1/2
8)
What characteristic of an electron does the magnetic quantum number
determine?
ml determines the spatial orientation of an orbital.
9)
