Cathode Rays Lead to Thomson's Model of the Atom

Regrettably, now the model is actually not perfect. An atom doesn't look like that pudding it once did anymore. The Yum Yum model is just out of date! :(

This title is anti-clickbate

i love you

🙉🙉🙉

What we see here raises more questions than it answers. I was looking for a ray and I see rising doughnuts of purple light. Also, do the electrons that were pulled off the cathode return? If so, how and when do they return? If not, where do they go?

how much is the vacuum in glass tube?

What happens after you turn the power off though? ... I mean during the experiment all the electrons are "sucked out" of the cathode if I understood that right? What remains? Will the cathode be forever positively charged after we cut the power? Or how do the electrons get back to the cathode?
Where do the electrons go during the experiment? Will they just stick to the anode and remain there as long as there is power?

Plum pudding but plum as -ve and remaining +ve so great

So electron can travel without ionising?

Great

NO

hydrogen

حد هنا ٢ ثانوي؟؟😂😂😂

I’m gonna apply a high voltage to my plum pudding to see if any plums come out

❤️❤️❤️❤️

What is the speed of electrons in cathode rays?

This raises so many questions:

1) If they were expecting to see "nothing or a spark", how come they saw they "saw the same glow no matter what metal they did the experiment"?
2) How on earth did they measure the size of this particle to conclude it is smaller than an atom?
3) When does this particle (electron) become a photon and how does that conversion work?

He's so cute

Still didn't show how charged 'particles' exist except from a quote by JJ Thompson..... Show us proof that electrons exist

This guy might become a great channel a decade later

Very good! Now can I have some pudding?

I dont know if there is an electron i only see a a purple colour 🙄 how identify?

I am doing personal research into the possibility of the vaticans chronovisor, and thus far ive been able to deduyce that seeing events that have already happened will always happen. So if one small component of this device works why cant the whole thing? All of this was considered a conspiracy hundreds of years ago, but so were many other things of those times which we now wildly accept.

Good job 👏👏👏

And the class gets blasted with X-rays. ☢️

Loved that ending perfect preparation of nuclear chemistry.

How the uniform dark spaces produced can you explain

What gave Geissler the idea for this particular experiment in the first place? What was his hypothesis

Consistency pays...

Thomson was relentless in his pursuit

Les électrons sont les raisins secs de l'atome!

why i’m i getting recommended to 13 year old video

Good

I use the garbage

Seeing young Veritasium is something veryy delightable

Jazakallah

"Electromagnetic Fields and Waves" by Lorrain & Corson (2nd Edition) contains a problem in chapter 2 "Electrostatic Fields in a Vacuum" (2-19) on J.J. Thomson's "Plum Pudding" model of the atom. It asks to (A) find the force on an electron; (B) describe its motion; (C) the frequency for a 1 Angstrom-sized atom; and (D) compare this frequency to that of visible light.

A rather thought-provoking question in an Undergraduate E&M textbook!

13 yearsssssssssssssss

its not complete vacuum. so there are some gas molecules or atoms present inside which are hit by electrons. once the electron of excited atom gets back to lower energy, it glows.



or charged particles whem accelerated emit electromagnetic radiation.


anyone?

the father , the son and the holy particle or wave or both

Well done!

See the hardworking of 13years

Okay I have a question here. Knowing that atoms are neutral, and we have cathode rays here, where are the anode rays? Shouldn't they appear too?

nostalgia ❤❤ ignorance is a choice in the age of information 😉

Why do these vids show up after a decade 😢
