Thomson had an inkling that the ‘rays’ emitted from the electron gun were inseparable from the latent charge, and decided to try and prove this by using a magnetic field. His first experiment was to build a cathode ray tube with a metal cylinder on the end. This cylinder had two slits in it, leading to electrometers, which could measure small electric charges. He found that by applying a magnetic field across the tube, there was no activity recorded by the electrometers and so the charge had been bent away by the magnet. This proved that the negative charge and the ray were inseparable and intertwined.
oh hello there
@Kbug can you rephrase your response pls because it's for a research essay and i need it thanks
@Kbug @Kbug @Kbug @Kbug
sorry i forgot bout u
I'm horrible at chem, I apologize but I don't want to mislead you.
idk sorry :P
josh u said u can help?
I NEED HELP SERIOUSLY
Hmm.. Sure, I'll help you but I won't actually answer the questions.
I'd look this one up in your notes. Remember that you can find the history of the atom and both the Crookes tube experiment on Wikipedia.
i know, the other guy copied and pasted from the internet
THOMSON’S FIRST CATHODE RAY EXPERIMENT Thomson had an inkling that the ‘rays’ emitted from the electron gun were inseparable from the latent charge, and decided to try and prove this by using a magnetic field. His first experiment was to build a cathode ray tube with a metal cylinder on the end. This cylinder had two slits in it, leading to electrometers, which could measure small electric charges. He found that by applying a magnetic field across the tube, there was no activity recorded by the electrometers and so the charge had been bent away by the magnet. This proved that the negative charge and the ray were inseparable and intertwined. THOMSON’S CATHODE RAY SECOND EXPERIMENT Like all great scientists, he did not stop there, and developed the second stage of the experiment, to prove that the rays carried a negative charge. To prove this hypothesis, he attempted to deflect them with an electric field. Earlier experiments had failed to back this up, but Thomson thought that the vacuum in the tube was not good enough, and found ways to improve greatly the quality. For this, he constructed a slightly different cathode ray tube, with a fluorescent coating at one end and a near perfect vacuum. Halfway down the tube were two electric plates, producing a positive anode and a negative cathode, which he hoped would deflect the rays. As he expected, the rays were deflected by the electric charge, proving beyond doubt that the rays were made up of charged particles carrying a negative charge. This result was a major discovery in itself, but Thomson resolved to understand more about the nature of these particles. THOMSON’S THIRD EXPERIMENT The third experiment was a brilliant piece of scientific deduction and shows how a series of experiments can gradually uncover truths. Many great scientific discoveries involve performing a series of interconnected experiments, gradually accumulating data and proving a hypothesis. He decided to try to work out the nature of the particles. They were too small to have their mass or charge calculated directly, but he attempted to deduce this from how much the particles were bent by electrical currents, of varying strengths. Thomson found out that the charge to mass ratio was so large that the particles either carried a huge charge, or were a thousand times smaller than a hydrogen ion. He decided upon the latter and came up with the idea that the cathode rays were made of particles that emanated from within the atoms themselves, a very bold and innovative idea. https://answers.yahoo.com/question/index?qid=20120110233243AAVXKEQ NOTE : Read and Write According to your views !!

Emo kids dont help anymore... i give up on helping..
Wait, can u say your opinion about Thomson's Cathode Ray Experiment ? WARNING: AVOID MASS TAGGING !!
he taged everyone on Open study :/
i need help not links and yes you can state your opinion
@tywower WARNING: AVOID MASS TAGGING !!
aye aye captain
can you help me @Wendysbro ?
I'm not quite sure. I'm better with stuff like math, history, computer science and basic to somewhat advanced chemistry.
hi @Afrodiddle can u help me w/o using the internet
such as copying and pasting
will u do ur own research and stop trying to cheat?
umm im not cheating im supposed to get help not get unreliable information off the internet
especially from wiki
i just want some help that's all
Regardless.. not everyone on OS is reliable.
well i guess so.. goodbye for now then.
use Brainly, it is more realible
