Thanks for the explanation
I read it in school when i was 16 , but I got to understand it today when I am 30. thanks mate , keep posting brilliant stuff.
you just revived my braincells thank you
You're very welcome! Thanks for watching!
Hey everyone!
I've noticed that this video has gotten a lot of views recently compared to my other educational videos, and I'm curious as to why that is.
How did you discover this video? What brought you here?
Any insight would be greatly appreciated.
Thanks!

My teacher linked this...
Hello, I am learning about this in my chemistry class so I'm watching a bunch of videos about the subject to try and understand it. This video really helped piece everything together, thank you!
my teacher had us watch this for a chem lab
Omg I just realized this comment was made 2 days ago. Well for me, I have midterms next week and I need to understand this topic for lab lol you made it super easy to understand, thank you!!
Search bar: atomic emission spectra
THANK YOU OMG. I was with 3 tutors and a hundred websites, and everything makes sense in 2 min.
thank you. i have exam 2morrow and i will do well bcos of u werry much thank
just an update friends... i got 95
Damn! It finally makes sense, wow. Thanks a lot, Ben. This surely helped me a lot
You're very welcome! Thanks for watching!
@@BensChemVideos Just had one doubt; that why is there dark spaces between the colored lines? Is it because of the wavelength of the photon being outside of the visible range? Help appreciated.
@@soumyashreebiswal14 It's because the atom, after absorbing energy, emits photons that have specific energies and, therefore, specific wavelengths.
@@BensChemVideos Got it! Thanks again :)
Ponting what you doing here man😳😳
I love thisso simple and straightforward linking concepts together
I've tried to comprehend the spectral line series from the beginning of my syllabus, this one was that one video that changed the how I look at atomic model. Holy Cow! Thank you so much
You're very welcome! Many thanks for watching 😀
Outstanding, comprehensive explanation!
Many thanks! 😀
This is a great video! It helped me understand this topic very well!! Thank uuu :)))

Hi! please do a video on Rydberg's constant! you explain very well, so we all can understand that thing better. thanks!!
05:35 where is that video? i want to watch it
This is fantastic, thank you!!!
Thanks from India 😍🤩
Its really help
Happy to help!
Wow !!! I love this simplified explanation. Amazing :)
Thanks so much for your kind words!
Very much appreciated, Like and Fav. Thanks for the vid!
Beautifully explained! Thank you so much

@@BensChemVideos No problem! Stay safe and take care :)
Best explanation ever!!! Thank you 😊 💓!
You're very welcome! Thank you for you kind words 😃
best explanation
Many thanks! Glad you enjoyed it 😀
Excellent explanation.
What makes the de excitation of electrons from higher state to lower states? Coz it's being continuously getting energy to be in that excited state.
Thank you very much! Great video and nice explanation
You're very welcome! Many thanks for your kind words 😀
the electron in hydrogen atom doesn't occupy the second, third or fourth energy level. how does it move to a higher energy level then returns to the 2nd, 3rd, 4th energy level?
Amazing simply amazing. By the way can you make a video about the quantam wave structure of the atom please.
Hey! Thanks for your kind words!
I actually have two videos that might interest you. One is called "Orbitals and Quantum Numbers", and the other is called "The Shapes of Atomic Orbitals"
I'm not sure if I can give a link in a comment, but I'll attempt it below. If not, then both videos can be found in my "The Quantum Mechanical Model of the Atom" playlist, which you can find on my channel page.

Thank you 😀
Always perfect timing, thank you :)
Liking ur comment so u will remember ur high school years
why do electrons further from the nucleus have higher energy than those closer? 3:24
Good question!
Electrons further from the nucleus have higher energies than those closer to the nucleus because the positive charge of the nucleus stabilizes the negative charge of the electron. More distance means less stability. Less stability means higher energy.
This phenomenon is known as Coulomb's Law, which states that the potential energy of two oppositely charged point charges increases with increasing distance between them. You may want to look up the Coulomb's Law equation to get a better understanding of this.
I hope this helps! 😃

Underrated video!
Thanks for your kind words, and thanks for watching! 😀
Great explanation! thanks Ben
My pleasure! Thanks for watching 😃
Is there a cut off element where you can no longer quantify the light absorbed or emitted using visible light wavelengths? (ex. after the 10th element, the light released can no longer been seen with the naked eye)
great video. may i ask. did bohr use his understanding of spectra to create his model? or was he just spot on, and so his model can be explained using spectra.
can you use this for applied science
Thank you!
Excelent video!
This was amazing! Is an orbit different than an electron shell? I noticed that you used hydrogen as an example which only has one shell… Yet it gives doesn’t give off a red colour? Is it a separate concept? Thanks!
You are a master
Happy Teacher's Day sir!
very nicely done! is the contemporary model the standard model?
my class is using your video you must be doing something right
When hydrogen atoms heated, atoms are supposed to gain energy right? If so, electrons should not attain lower levels and shouldn't give off photons??
Also, Ben, why it it that the electrons of hydrogen atom on being heated falls to lower levels and give off photons instead of attaining higher levels.
I don’t
Very helpful thankyou
the only video that actually made sense to me thank youuuuu!!!!!!!
Hello, it's a really great video.
I just wanted to ask...may I use 2-3 slides of this video for a non-commercial...social service kind of purpose? If you don't mind?
Thanks for your kind words! You're welcome to use the video however you like.
-BeN
Super helpful thanks
This is such a great video tysm!
too good
Could someone explain how an electron from H can go from say the fourth orbit to the first? Isn't it in the 1s orbital and hence n=1 so how could it be in the fourth
I asked my physics teacher the exact same question. Apparently, every atom has all the possible orbitals. The quoted orbitals - 1s2, etc. - are average positions, not places they are guaranteed to be. So they can move from any position from any other position, as far as a limit. Beyond that limit, they leave the atom and the atom is an ion. This freedom to move to many different places explains why hydrogen has many lines on an emission spectrum: one line corresponds to an electron falling from n = 2 to n = 1 and another is from 3 to 1, 3 to 2, etc.
I know the hydrogen atom was just an example but, why did it have six shells instead of just the one?
Thank you
amazing!!!!
Thanks for your feedback! And thanks for watching! 😀
Man I love u
Thanks! 😃
Which Video Editor you are using?
Camtasia...can't remember which version since it was so long ago
@@BensChemVideos Thank you
@@BensChemVideos lots of love ❤ from India🇮🇳
Thank you Ben : )
Does electron always gets excited to specific energy level or it can reach any random energy level?
Did u get the answer of this question?
Are energy levels of all atoms same?
Like energy gap between N1 and n2 is same of for all atoms or it differes
No, it's different for every element.
Can you explain how it changes
thanx so much
very very helpful thank youuuu u saved my life
i don't understand how there could be multiple lines of light emitted when there's only one electron... someone pls help
If you're observing a sample of, let's say, one mole of hydrogen, then that's 6.022 × 10^23 hydrogen atoms that each have one electron. So there are tons of transitions all happening simultaneously.
Does that help?
@@BensChemVideos so one atom of hydrogen will only emit one light line?
@@annamars1931 one line at a time, yeah. However, the transitions happen very quickly. It's kind of like a ceiling fan on its fastest setting. You don't see the individual fanblades, but a big circular blob.
Hey Ben, how come the spectrum of He+ resembles that of H? Also, should not the spectrum of He also resemble that of H since the 2 electrons on He are in the sub-shell as that of the electron in H?
I invite you to consult ( Atomic model 2020 Hydrogen ) electrons doesn´t orbit around atomic nucleus, thys oscilate or vibrate !
Thanks for the invite!
I love you!
Great explanation thanks a lot
Why don't electrons get excited to random energy levels and produce different spectra each time?
Then how can absorption lines change to a different part of the spectra and still represent the same elements, as in a red shift? How can they know they represent the same element when they appear to be a different color?
change my mind: bohr looks like seinfeld
Ok then :)

Who's here after Samir advise?
I have 16 minutes left on my test
Good luck!
What is up guys?????
Sky full of star
U look like lex luther

anyone here from 2024
i like it how you explained with your emotional face..🤣
America has win zat ho oqat ho
Ben. Pls be gay 😭 im in love with how u speak
