Thanks a lot ! It really helped me while doing basic concepts of chemisty needed for my JEE prep. ... I felt the topic confusing but your soothing voice n elaborate explaination made it quite easy . ❤
Your videos are have an inspiring effect on me. I get insightful ideas when playing them in the background even without listening attentively. I think it is the gentle female voice.
You claim that the mass of Helium atom is 1/3 of carbon 12 mass or hydrogen mass is 1/12 of carbon 12. Forget about the theoretical explanations using protons and neutrons idea. My question is on what practical and experimental bases are you making these comparisons. How much have you collected from each to make such a comparison? Did you use analytical scale? Thank you
Do you collect 12 grams of carbon 12 powder? Hydrogen is a gas, then how much hydrogen gas in volume do you collect in order to weigh it and make caparison in mass with carbon 12 and come to the conclusion that the atomic mass of hydrogen should be 1, meaning 1/12 gram of carbon 12? Carbon is solid where as hydrogen is a gas? As I watch your videos, I will have more questions to ask. If I may provide you with my email, is it possible I can have email correspondence with you in order to address my questions directly to you? Thank you
Hold one...; this old lady has a "need to know!" Please; don't brush over steps, (explain how to find...) Carbon 12. My table displays Carbon-Cu, within the Transition Elements, so are there additional Elements noted on a broader diagramed Periodical Table? The Math symbols; could you state them/explain them as you write them. Also; what does 10 to the neg. 23 mean? I take it as minus.
Hi Robin! You might like to start with our Periodic Table video, to understand how it is organized: bit.ly/PeriodicTabl To understand what "10 to the negative 23" means, try our video on scientific notation: bit.ly/SciNotat Thanks for watching!
My school was pretty terrible, I they haven't teacher even the basics (just for you to have an idea, I haven't heard the word "protein" a single time at school) so I'm learning on my own now.
It helped me very much. I will always support you to continue showing such wonderful videos I am watching your channel from an arabic country 🇶🇦 Qatar thanks alot ❤❤
![What is Atomic Mass & Mass Defect on the Periodic Table? - [1-2-9]](http://i.ytimg.com/vi/XLCupmUZimY/mqdefault.jpg)
Finally, an explanation I can understand of why using carbon 12 as the atomic mass standard is so important! Thanks!
😂😂😂😂😂😂😂😂😂true true!

This was so much easier to understand than my uni lecturer. Thank you so much
Very clear simple explanation. Excellent.
We're so glad you found it helpful! Thank you for watching!! 💜🦉
Thank you .. that was amazing .. finally I understood what amu
is ..finally ..wonderful video
Thanks again 🌸🌸🌸🌸🌸
We're so glad our video was helpful! Hearing this always makes us want to make more videos!! :D
This video deserves more likes
Very nice explanation
Beautifully explained
nicely explained
It's the mass of proton, neutrons or electrons are constant or they differ by the atom

We're so glad you've found us!! Thank you for your kind comments :D
Resolved Most of the Doubts.
You claim that the mass of Helium atom is 1/3 of carbon 12 mass or hydrogen mass is 1/12 of carbon 12. Forget about the theoretical explanations using protons and neutrons idea. My question is on what practical and experimental bases are you making these comparisons. How much have you collected from each to make such a comparison? Did you use analytical scale? Thank you
Thank you !
It's totally clear, and well explained.
We're so glad we could help! Thanks for watching!! 💜🦉
and how can you find that the mass of helium is the onethird of the mass of carbon atom
Very helpful 👍
Do you collect 12
grams of carbon 12 powder?
Hydrogen is a gas,
then how much hydrogen gas in volume do you collect in order to weigh
it and make caparison in mass with carbon 12 and come to the
conclusion that the atomic mass of hydrogen should be 1, meaning 1/12
gram of carbon 12? Carbon is solid where as hydrogen is a gas?
As I watch your
videos, I will have more questions to ask. If I may provide you with
my email, is it possible I can have email correspondence with you in
order to address my questions directly to you? Thank you
Where is the bit about Daltons... someone tell?
Thank you
You are so welcome! We're so glad you found our video helpful. 💜🦉
Nice,thank you and also you have a beautiful voice
Very helpful mam👍
Thank you very much for the video. Could you please tell me the name of the song playing? Thank's again.
+Colette A Isn't it pretty!? It's "Sentimental Waltz" by Tchaikovsky. Thanks for watching!! :)
Thank you! It is very touching indeed!
Thank you so much.
Very nice thanks
Thank you for watching! :)
Did I miss Da being mentioned?
nice
thanks
wow i understand how carbon 12 classified thnks
+maxamed muxudiin We're so glad you found our video helpful! Thanks for watching! :)
You have explained the best in the whole RUclips
Thanks🥺

Hi,can you explain how the value, 12U = 2*10^-23 is derived
