Sir I am heartfully thanking you for this amazing video.. my mam = 45 minutes class U = 45 seconds class, however video is for 2 minutes I understood in 45 seconds.. amazing lecture keep going..
I dont get it, what if you arent given the neutron? And told to find the atomic mass.. I know to find it you need to add the neutrons plus the protons (correct me if am wrong lmao pls) but how do I find it If I dont have the neutron either HELPPPP
Do you mean the mass number of isotopes? If so, there is one at: ruclips.net/video/cHs5aNtiYUI/видео.html - let me know if this is not what you mean! Hope it helps, and thanks for subscribing!
Thank you very much sir. This video will be a great help for my future lesson. I am humbly asking your permission to used your video in my online class. Is it ok with you? Hoping for your kind approval regarding this matter. Thanks again Sir.
Haley Wright Different periodic table have it different ways. In the UK, the atomic mass is at the top. The key is to find the largest number - that's the atomic mass, and the smallest number is the atomic number. Get that right and the rest is to same wherever you are!! Hope that helps!!
Thanks for the feedback! I have since purchased a new mic - my latest videos are a lot clearer. Will look to redo this one day - once the others are complete!
It depends on the Periodic Table - some have it above, some below. The key would be to remember it's the smaller number of the two. For the GCSE I teach (Edexcel) it's the bottom number.
It depends on the periodic table you look at. In the UK, the atomic number is always on the bottom - which is where I teach. Either way, the atomic number (protons) is always the smallest number and the atomic mass is always the larger number
Only if you have an ion. This video is focusing on Atoms - where all protons and electrons are the same. It will specifically state if you need to describe for an atom or an ion.
Thank you finally someone who explained it properly :)
Glad it helped!
true
Protons: 22
Electrons:22
Neutrons:42-22=20
This make me so comfortable
Davium
Protons : 22
Électrons: 22
Neutrons 20
That is correct! Well played!
Finally i am understood
You teaching style is very good
So thanks 💯💯💯💯💯
Thank you for the clear explanation.
stfu

Glad it helped :)
I have been struggling to grasp this. With the way that you explained it its actually simple. TYSM
I’m so grateful for this wonderful explanation and i can now pass my checkpoint exams.
Thank u 💓 may God shower 🚿 u with blessing ameen🤲🤲🤲

Wow this was 8 years ago but so easy to understand! Thanks! I got a good grade on my homework and test!
Thank you so much for making it easy for us.. 😊
hi sir love your videos keep it up! my g
how does this not have more views or likes, thankss
I am from india and I like ur teaching style 🙂
Thank you! 😃
thank u mister barnes this was vary help full
Glad it helped!
thanks really helped me study for a test
You're welcome :)
Thank you so much for best explaination
I like it its short and simple
thanks
what year you in?
Can you plz upload a video of how to calculate the mass number? Plz thank you ! I have already subscribe !! Great video

Yes it it! Thank you so much! Plz upload more video about chemistry!! Thank you so much !! Best video ever! Clear explaination !
Thank you badiya yar ma full marks le aaaya
Great! Glad I could help!
Thank you so much .🙏
U explained in such an easy way that I understood it instantly .😁
Why you minus 4 from 7 in no. Of neutron
Thank you very much sir. This video will be a great help for my future lesson. I am humbly asking your permission to used your video in my online class. Is it ok with you? Hoping for your kind approval regarding this matter. Thanks again Sir.
Thank u very much u really helped me with this!
Thank you
You are very welcome!
mr barnes you a real one
Thank you!
thank you for simple explenation
other videos about this one pleas
Since when is the mass number on the top?! And the atomic number on the bottom this doesn't make any sence
In the UK, and some other countries, it is this way. That's why I always say that the atomic number is the small number.
Thank u for sending video
Nice one g
Thanks 💯
Thanks very informative
:) Glad I could help!
Thank you sir
Thank you Mr ❤️
not me sat hear watching this the night before my gcse
thankyou sir finally i got it
Great to hear!
Thank you thank you very much sir
Love from india ❤️
HI MR BARNES IT'S CLARE
Hey it is sky
hi its maya
Hello everyone! Hope you are all keeping safe!
Thanks
😢😢😮😮
sir thanks for the explanation it helps me ...
Glad I could help!
Thank u sir
After seeing comments I can say that most of people is from India and me too
Short and sweet 😍😍😇😊
Thank you si
Ty sir sooooooooo much
Thx it was helpful
Nice video
Thanks! Appreciated!
Thnx
No problem! Glad you found it useful!
💀Huh? That is so wrong the atomic # is at the top and the atomic Mass is at the bottom
Haley Wright Different periodic table have it different ways. In the UK, the atomic mass is at the top. The key is to find the largest number - that's the atomic mass, and the smallest number is the atomic number. Get that right and the rest is to same wherever you are!! Hope that helps!!
Mr Barnes oh ok
voice is not cler...
Thanks for the feedback! I have since purchased a new mic - my latest videos are a lot clearer. Will look to redo this one day - once the others are complete!
Thanku
p=22 E=222 N=20
That is correct! Provided you meant 22 for electrons and not 222!!
And the last no of neutron is 20
Thankyou
thanke for my help it was so diifiicult but i saw it is correct
Glad I could help!
Proton would be up number how it' could be down number
It depends on the Periodic Table - some have it above, some below. The key would be to remember it's the smaller number of the two. For the GCSE I teach (Edexcel) it's the bottom number.
Not really the smaller number it can be the same for example hydrogen since you round it. =_=
Agreed. However hydrogen is the only exception here. The general rule is smaller = proton number, larger = mass number
Yeah I know that :)
thanks, really helped!!
Great :) Glad I could help!!
Thank u so much
thanks ,
You're welcome!
vvt =very very thanks
VVW! You're very very welcome! Glad I could help!!
Da p 22 E 22 N 20
I think its the opposite the total pof protons should be on top
It depends on the periodic table you look at. In the UK, the atomic number is always on the bottom - which is where I teach. Either way, the atomic number (protons) is always the smallest number and the atomic mass is always the larger number
vvt
24+8-8=24 which is kobes number kobe is the goat
The way you tought was easy to understand my concept is clear. Thnq.
I scored 6/6.😍😀
Thanks! Glad you found it useful!
@@MrBarnesTC thanks Man
Thank you
Thanks
You're welcome :)
I am from India this video is too good ☺☺☺☺☺☺
Thanks! Glaf you found it useful!
Love you... can you share my you tube channel on your social media ... for me plz☺☺☺☺ love you
I am also from India. your voice is so clear .❤.
thanksssssssssssssss !!!!!!!!!!!!!!!!
it is so help ful pls up load video of calaulating average atomic no
Guys sometimes the number of the electrons no same with protons because it can be (un)ntural.
Only if you have an ion. This video is focusing on Atoms - where all protons and electrons are the same. It will specifically state if you need to describe for an atom or an ion.
Thank you so much
Great video
thank you for clearing my doubt
Happy to help
Your a GOD
Haha. Wouldn't go that far! Glad it helped though!!
