
(Two parts) The Lewis dot structure shows us what? Specifically, what do the dots
represent? Draw the Lewis Dot structures for the following:

Energy Problems:
Equations and constants:
E = h and E = hc/
E = energy of one photon with a frequency of 
c = 
c = speed of light = 3.0 x 108 m/s (meters per second)
c/ = 
h = Planck’s constant = 6.63 x 10-34 J-s
 = wavelength in meters
 = frequency in Hz (waves/s or 1/s or s-1

Calculate the frequency of light that has a wavelength of 4.25 x 10-9m. Identify the type
of electromagnetic radiation.

