Question

Chemists in the 19th century constructed an evacuated glass tube with wires
inserted in both ends. When an electrical current was generated at the anode, a
'cathode ray' would pass to the cathode creating a fluorescent glow. These
experiments helped chemists better understand the nature of the electron.
J.J. Thomson added a magnetic field to a cathode ray tube to show that the ray
would bend. His experiments demonstrated that the rays were negatively charged
particles. He then calculated the mass to charge ratio of the electric ion (electron).
According to his calculations, how massive was the electron relative to the
hydrogen ion?
Voltage Source
A) The same size
B) ~1000 times larger
C) ~1000 times smaller
+
S
D) ~10 times larger
Anode
Cathode
E) ~10 times smaller
