Millikan determined the charge on the electron by studying the static
charges on oil drops falling in an electric field. A student carried out this experiment
using several oil drops for her measurements and calculated the charges on the drops.
She obtained the following data:
Droplet Calculated Charge(C)
A 1.60 ✕10-19
B 3.15 ✕10-19
C 4.81 ✕10-19
D 6.31 ✕10-19
A. What is the significance of the fact that the droplets carried different
charges? [4 marks]
B. What conclusion can the student draw from these data regarding the charge of
the electron? [4 marks]
C. What value (and to how many significant figures) should she report for the
electronic charge? [4 marks]
Question 2: Use VSEPR theory to predict the molecular shape and the polarity of
SF2. Explain your answer. [4 marks]
Question 3: Draw a Lewis structure for PCl4 . Use VSEPR theory to predict the
molecular shape of this ion.?
