Sir,we know that atomic number is same but atomic mass is different is called as isotopes And, Atomic number is different but atomic mass is same is called as isobars In above lecture At 6:13. Sec this may same mistake
6:00 you are wrong, isotopes are yhe ones that have the same atomic number but different mass number Trick to remember - isoTOPe so the top is changed which is mass number .
Arvind sir u are great 😍.... I watched soooo many vdos but could not understood the concept but because of you I completely understood it in 25 mins.... Thank you🙏💕 sir ❤ god bless you🙏💕
Sir sorry to say but I think isotopes have same atomic number and different atomic mass , and sir has said isotopes have same atomic mass ,plss someone correct me if I'm wrong
Firstly we findout, 1mole=molar mass or atomic mass so we have to know molar mass And when we find out molar mass we should know mass of 1 mole then what was found first 1 mole or molar mass please explaine
Before this relative mass how they use to calculate the mass of atom Moreover how they calculateed mass of carbon in the first place... And why it is hard to find the mass of each atom through mass spectrometry Why do we need to move toward a relative system of this mass calculation
Sir aapne bola ki isotope ka mass number same ho or atomic number different h jo ki galat h aur isotope ve hote h jinka mass number different ho aur atomic number same ho at 6:05
Whenever I search a topic from chemistry I use to write Arvind Arora at last... If same thing happens with anyone hit like.. 🥰🥰🥰🥰🥰 Salute to the art of your teaching.. Love you sir ❤❤❤❤❤❤❤❤❤
Are relative mass kaise nikala? Sample kis state mein lete hain? Usmein number of particles kaise calaculate kiya hoga? Uske bina atomic mass nhi pata kar sakte. Na absolute na relative!

College?
Yes
Arvind arora sir ❤❤❤❤❤❤❤❤
Best chemistry teacher ever, lots of respect to sir.
Ye sir bhi best hai lekin mere skool k sir vo bhi ek dm super duper best vale
In sir ka youtube show hai jisme is channel se jayda subscriber hai
sir is saying that isotopes have same atomic mass and different atomic number but it is wrong.... then how he can a best teacher.....

You are Right❤❤❤❤❤😊😊😊
Sir , u did a mistake
Isotopes hv same atomic no.but diff.mass no.🙏🙏🙏
Isotope ko bol ke inhone mujhe confuse kr diya
Jab apne bataya to mai 2-3 bar remind video kar kar deka ki akhir mai galat ho ya phir sir se mistake ho gaya
Haa
same confusion i had.
Hn, sir aapne hmko v confuse kr diya
Aaj tak aapse aaccha padhane wala nai dekha maine.
Thanks a lot sir for give your imp time for us

Mujhe lagta hai kuchh log sirf video me kya galti hai wahi dhudhne aate hai yarr sir ki padhai ka level dekho and enjoy it.❤
Very very well explained sir🙏🙏🙏salute to your teaching
niether my coaching teacher explained this nor my school teacher explained this well.
i am a student of class 9th and i had a dobut that why we use carbon to calculate the atomic mass but now it is clear😊😊
SAME
Isotopes -mass is different
-atomic number is same
Someone noticed at 6:6min
About isotopes
Sir has mistaken.
Isotopes have same atomic number but different atomic mass
Ab itna padha rahe hai to kuchh galti to ho hi jati hai
@@cbicentralbureauofinvestme9711 ha bhai

really a very helful video sir
❤ From Nepal
Itni video dekhi lekin aap jaise koi ni sikha paya🙏thanks sir from the bottom of my heart 😇rula ke rakh diya tha is concept ne
6:04 there is one correction -atomic number is same and atomic mass is different
Right bro
This is the definition of isotope wright 👍👍🏻
Exactly
6:05 isotopes have atomic number same but atomic mass different.
yes
Yes
Actually sir wo platinum-iridium cylinder tha Jo sevres ke ek measurement institute me rakha tha hai na?
Thank-you sit 😢
I was really struggling for it 😊
Sir really your teaching style is to much well... I want offline teachers like you
Very well explained, Thanks🙏🙏
You are best teacher
Please check the video and listen clearfully what you have told about isotopes.?
Sir sorry to say but I think isotopes have same atomic number and different atomic mass , and sir has said isotopes have same atomic mass ,plss someone correct me if I'm wrong
Yes
No words just amazing the way your comparison
Yes 👍
It was one of my most doubtful concepts😢....but you have cleared all of my doubts sir... thank you so much 🎉
Thanks sir... Itna acche se koi teacher nahi parhate hain...
Sir relative mass is mass of an atom compared with mass of carbon 12 then how it has unit of amu .when mass unit is cancelled by mass unit???????
Amazing content 🙏🙏🙏🙏🙏🙏 dhanyawad Sir jiii
Sir jo smjhaya hai na ....dil jeet lia ❤️...hmare dil mai aapke liye izzat or bhi jyda badh gyi 😂❤️👍🙏
I also think that your teaching method is gzzzbbbb🤓🤓🤩🤓😝😜😋
Very very thank you,
I am student of class 9 but still i am able to understand because of your way of teaching.....
Thank a lot✨
Way of understanding is much good
Legends are here by seeing Arvind Arora sir as we know him he is the best fact explainer , so he can also explain a thing properly .
What is the difference between atomic mass and average atomic mass and mass of an atom and atomic weight and relative atomic mass??
One correction isotope have same atomic no and different atomic mass
Exactly
Very nice sir ji aap bahut achha padate ho👍👍👍👍👍👍👍👍👌👌👌👌👌👌👌👌👌👌👌👌👌👌👌👌👌👌👌👌👌👌
Firstly we findout, 1mole=molar mass or atomic mass so we have to know molar mass
And when we find out molar mass we should know mass of 1 mole then what was found first 1 mole or molar mass please explaine
Sir agar mass of C12 Atoms = 12 amu!
Then mass of C12 baki Atoms se bhari hota hai kya ?
Isotopes are having same atomic no.but different atomic mass aap ne galt bola 6:04
Yes you are right I am also think about isotopes😅
👍 yupp..!!
sir jab maas gram me diya hoga to AMU me kyo converd karna hoga?..🙏🤔
Is the isotopes should have to the captain (C-12 atom) or not
Nice explanation sir
Property - Isotopes
Sir,, how we will calculate the a. m. u. Of sodium ,MAGNESIUM???
You are best teacher of the chemistry
Sir you are very best in the world
Sir by mistake u defined isotopes wrongly. They r actually the atoms of same element having same atomic no. But different mass no.
Silly mistake.
Ek tapakti boond aapki zindagi barbad kar sakti he 😁😁
Doesn't matter See the way of sir's teaching😄
Excellent. Sir. I. Very. Thank. Full. To. You.
I am in 10th class but I was confused at amu, but what an explanation he has. Just Awesome!
Before this relative mass how they use to calculate the mass of atom
Moreover how they calculateed mass of carbon in the first place...
And why it is hard to find the mass of each atom through mass spectrometry
Why do we need to move toward a relative system of this mass calculation
You are a great teacher 👌✨
Thanks a lot 👍👍👍
Best video on this topic......🤗🎆
Sir aapne bola ki isotope ka mass number same ho or atomic number different h jo ki galat h aur isotope ve hote h jinka mass number different ho aur atomic number same ho at 6:05
Sir bolo
Sir mashallah bht mahnat sa samjhaya ha ap na thank u sir
What is the difference between atomic weight nd atomic Mass ?
Good evening sir....thanku so much sir....🎉🎉😘😘😍😍😎
How's your prep going so far?
Thanku so much 😊😊
During this pandemic I wasn't able to understand anything but u helped me out, thank you so much.
My words r less than ur work. Thanks again.
student cant judge teacher who is good and who is bad because teachers have knowledge better than student thats why they are teacher
Wow that's the energy of a good teacher
yeah!
he is so good at teaching...
Sir you are the best teacher 🤗😊🤗
Thank you.. Video was really very helpful.
Sir galat bol diya thoda repeat kar dete isotops atomic mass different and atomic number same 6:03
Isotopes= Same atomic number(no. of protons), different atomic mass (no. of neutrons)
Thanks i got confused
The best way of teaching!!! Really impressive carry on teaching forever
App ko kase pata chala
I have a doubt as we all know A=p+n
And A, is the atomic mass but why we not include electron in atomic mass
Because number of electrons changes when an atom loses or gains electrons so their quantity isn't fixed
Love the way you teach sir love the way you teach 🔥❤️
Haai broo.... i have a dought can you clear please ?....
Your +1 exam starting date?
Bahut bdhiya sir❤❤ gjjb explained wahhh
isotope hota hai atom with same atomic no but different mass no ,lol, nevertheless, the video was good , thank you for your effort

Sir excellent method of your teaching
Sir , this is the best lecture on atomic mass i have ever found....now this topic is crystal clear for me...thank you very much sir....
Sir thanks apki wazese hume padhne me bahut help hote he
Really great technique of teaching
Isotopes are having same atomic no. but different atomic mass and not which have said sir.
Kabhi kabhi ho jata h
Why carbon is as a selected as a standard element for calculations of atomic masses? What is the reason sir.
Wow sir 🙋 🙋🍂 🍁👦 Kya teaching style hai ekk bar m smjha Diya 😅💁💁💁🙋🙋🔰 thank you so much....
Arvind sir is god father of chemistry. 👌 ek no. Sir. 😘
Sir you are role model for me. I follow u. U are awesome ❤️
Thank u so much Sir ji 😊
Sir description box me kaha question hai plzzx
Yes...kaha h question?
14:56, the scientists at that time were not aware of the mole concept, so how did they calculate the mass of carbon?
Best Chemistry teacher really .you made this topic very easy,a lot of respect for you 🙏🙏
😀nyc explanation sir👍👍👍
Thank u very much sir
Very good sir you are so amazing
You teach very basic to advance and
You are the best 👍👍👍👍🌹🌹❤️👍😀😀😀😀
Are short vale bhia 😂😂😅 aj tk sirf apke you tube shorts dekhe h phli baar koi concert dkh ra hu 😅🙏🙏
Yes bhai
From the basics to wow
Sir how will we find mass of one atom of any element for expressing it in amu
Sir u are best teacher 😊😊
thank you so much sir I was try to before 3 days to solve this problem but finally I am achieve the answer of this question to you 😘😘
