there are negative electrons on the outside of the atom
J.J. Thomson used a cathode ray tube to discover electrons. By passing an electric current through the tube, he observed the deflection of a beam of electrons, which led to his conclusion about the existence of electrons.
A "CRT" is a cathode ray tube. An old style computer monitor (not computer).
Electrons.
because cathode ray tube is the heart of the television.
The cathode ray tube was invented in 1897 by Ferdinand Braun.
J.J Thomson conducted the cathode-ray tube experiment in 1911.
Cathode ray tube amusement device happened in 1947.
Cathode ray tube amusement device was created in 1947.
None of these appliances use a cathode ray tube. Older type TVs used a cathode ray tube, its common name was the picture tube.
The cathode ray tube was not discovered it was invented by Ferdinand Braun
Probably a mis-spelling of "cathode ray tube".
The negatively charged electrode of a cathode ray tube (CRT) is the cathode. The tube is a cathode ray tube, and electrons stream off the cathode, are accelerated across the evacuated space and "directed" either electromagnetically or electrostatically, and then strike the phosphor coating on the positively charged anode at a "location" determined by the "directing" elements.
