Answer:
The metal plate, with the negative charge, is called a cathode. When the current was passed, he observed a greenish glow, near the anode. The particles, which were emitted from the cathode to the anode, was the cause for the greenish glow. The streams of particles emitted, from the cathode, are called cathode rays.

Answer:
Electrons were first discovered as the constituents of cathode rays. J.J. Thomson used the cathode ray tube to determine that atoms had small negatively charged particles inside of them, which he called “electrons.”
