The Historical Development of Atomic Theory

Question 1 • SVHS Chemistry 1 $FA

Which activity is the best demonstration of J.J. Thomson’s use of creativity in his work?

Answer
A
ignoring observations in his experiment
B
interpreting the results of his experiment
C
physically assembling the apparatus for his experiment
D
reading about Joseph Proust’s work

Explanation

Creativity in scientific work is especially evident when a scientist interprets results and develops an explanation from them. Thomson used his experimental findings to reason about the properties of cathode rays and propose the existence of electrons. Ignoring observations would undermine the investigation, while assembling apparatus or reading earlier work does not demonstrate this kind of creative interpretation as directly.
