Me polytechnic student hu... Aap bohot ache teacher ho.... Bohot achese padhete ho.... Agar. . apke jaise sabhi sar padhte to...maza aa jayega ... Thank you sir... You are the best
Very useful video. Very simple way teaching. I am 34 years old. I have attended 2 class. I will surely recommended others due to sound voice, clear presentation in very simple way. Thanks u very much for sharing this type of video.
One of the best person who has described the concept so clearly that no other can match his efficiency!!! Wish u were in our childhood time!!!! Highly appreciated
thank you, sir I was trying to understand what is valency since 5th grade but could not understand it but after this video it was completely easy to understand.🤯🤯🤯🤯😌😌😌
This channel is a one of the best science channel on whole youtube really sir you are great you don't waste any type of time you are sharing only knowledge I like this please sir aise he batate rahiye details me
@@edupoint.secondary Sir I am studying in ssc board of maharashtra. In my textbook, there is only introduction of variable valency, but I didn't understand. And I also want to learn full concept of variable valency.
Sir 1. configuration of beryllium is 2,2 so it's duplet is completed so why he wants to lose electron? is it not a noble gas as helium with configuration 2 is? 2. Why atoms wants to be stable? Plese if anyone knows the answer reply becaus it help me a lot please sir you also 🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻
The maximum electrons of 1st shell is 2 and of second is 8. Helium has the atomic number 2 so, if it is a duplet, then it's valence outermost shell is filled. Hence it will not react But in beryllium, the atomic number is 4 and if it wants to fulfill the valence electrons, it needs total of 10 electrons and it is having only 4 That is why it reacts
Thanku u thnku So much sir mujhe valency ko solve krna bilkul smajh nhi aa rha tha but apki vdo ko dekh kar smajh aa gya thank u very much sir ❤😅😌💮👨🏫💫💫✨✨✨
pehle to bhai atomic number ydd kar lo..... then uska electronic configuration nikalo aur jo ocatate ko fulfil karne ke jitne electrons ko loose karna hai ya gain karna hai wahi uska valency hoga.......
Sir! Is structure formation me jo two different atoms kisi bond ke through attach ho rahe hain to uss formed compund ki naming kaise decide hoti h like: Sodium chloride ko chloride sodium kyon ni mention kerte????
You are the best teacher rather than my school teacher.
We are agree with you.
Correction - better
Yes bro

Every Teacher is best
You teach slowly, but that gets permanently fit in brain 🤗🤗🤗❤️
Sir abhi bas main 15:48 pr hi hu but still I'm fully satisfied by the concept of *valency* you're best genuinely... ☺️☺️
Thank you so much , you explain in the best way than our teachers and other youtube channels
Very useful video. Very simple way teaching. I am 34 years old. I have attended 2 class. I will surely recommended others due to sound voice, clear presentation in very simple way. Thanks u very much for sharing this type of video.
You animation make chemistry more faceneting and intersting ❤❤
*Sir u cleard my all doubts ...tnks a lot sir....*
Sir you're fantastic teacher....you know what itni saari video dekhne ke baad ab apka video dekh kr doubt clear hua...🙏
Same Babu
Sir, you are really an excellent teacher. आपको कोटि कोटि प्रणाम🙏🙏🙏🙏🙏
Nicely explained.. Thank you teacher👩🏫 😃
Sir your explanation is best all over here... And sir your TH-cam channel should be more popular In educational video 😊
Love you teacher ❤❤

Wait for specific stage you will understand everything
are sir aapko kya batau 6:00 meri puri chemistry ke L laga diyee thanks sir you are grate

Excellent teaching sir👌.
Pls make a separate video on variable valency.
Variable valency in Std 9th???
Wow....
Which board are you studying under???
@@edupoint.secondary Sir I am studying in ssc board of maharashtra. In my textbook, there is only introduction of
variable valency, but I didn't understand. And I also want to learn full concept of variable valency.
And I like your teaching.
You are teaching best sir👌👌👌👌👌👌👌👌❣️
You are the best teacher I ever seen you can explain all things properly
You are also best teacher 🙏🙏
Your videos clear my doubt like a crystal clear.
Thank you so much sir.
Hi seema
sir ji kyaaaa ada te hai aap manna padega 👍👍👌👌👌👌
Superb 👌👌thanks,
Keep growing sir...
Good day all of you class 9th
Excellent and very useful video, Arijit sir. Thanks a lot. You are a Unique teacher. Take care of your health.❤️❤️☺️☺️☺️👍👍❤️❤️🙂🇮🇳🇮🇳
You are the world best teacher,..sir please start practice session video ,in chemistry from 1november
Beauty lies in the eyes of the beholder.
🙏🙏🙏🙏
Love from Bangladesh🥰 Thank you sir.Just wow!❤️🥰
Superb
Sir aap chemistry bahut badhiya padhate ho
Sir 1. configuration of beryllium is 2,2 so it's duplet is completed so why he wants to lose electron? is it not a noble gas as helium with configuration 2 is?
2. Why atoms wants to be stable?
Plese if anyone knows the answer reply becaus it help me a lot please sir you also 🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻
Duplet stability is only for the 1st shell as it has only the s orbital.
The maximum electrons of 1st shell is 2 and of second is 8.
Helium has the atomic number 2 so, if it is a duplet, then it's valence outermost shell is filled. Hence it will not react
But in beryllium, the atomic number is 4 and if it wants to fulfill the valence electrons, it needs total of 10 electrons and it is having only 4
That is why it reacts
Thanku u thnku So much sir mujhe valency ko solve krna bilkul smajh nhi aa rha tha but apki vdo ko dekh kar smajh aa gya thank u very much sir ❤😅😌💮👨🏫💫💫✨✨✨
Very talented sir ho appp
The video was very helpful

Sir i am one of your oldest subscriber,Sir i request you to make a video on variable valency, The concept of variable valency come in the olympiads...
You the best teacher I ever meet in this channel thank you sir .
Thanks you so much sir
If i watched this type of explanation in 12th , i got really better marks .... 😞😞bad luck , so good luck students..... It helps u moreeee...
Thank you so much sir🙏🙏🙏🙏🙏🙏🙏🙏🙏
Nice info 👍
Best chemistry teacher
First like to my favourite teacher 👍
Very good explanation sir . You have cleared my all doubts . Thank you so much sir 🙏😇
sir why doesn't hydrogen have a neutron?
sir the video was very informative and helpful.
thank you
it has only 1electron.
Thank you sir you are the best📝📝
Thank you sir your explanation is excellent I got cleared my all doubt
सधन्यवाद गुरू जी
Thak you sir for explain this thank you very much 🙏🙏
Great job 👍
really sir you are great
Make 10th physics and chemistry vedios sir please...
Thank you sir 🙏🙏🙏🙏 for giving your best knowledge it very helpful for us
Sir you are grate
Love ur deep explaination.
My teacher < edupoint sir
Thanks ❤❤❤❤❤
Too good.. Thanks a lot..
Sir please bataye how to remember valency & variable valency of every atoms.
pehle to bhai atomic number ydd kar lo..... then uska electronic configuration nikalo aur jo ocatate ko fulfil karne ke jitne electrons ko loose karna hai ya gain karna hai wahi uska valency hoga.......
Nice 👍👍👍
Thanks a lot it help alot 🙏
I am from Gujarat thanks
Thankyou so much siirrr tommmorow is my exam it was very helpful ♥️♥️♥️♥️🙏🙏🙏
Sr g bhot xber10 videos banaty ho lakin 9th or 10th ka pora course upload kia ha kia?
you are too good sir..
🙏 Thank you so much sir
Sir, do the shared electrons revolve?
Thank you sir ❤
Sir .I don't know . But I know you're God for me. Thanks
sir covalent bond mein common vaala electron dono atom ke around revolve karta hai??
Thanks a lot sir ji
😅😅😅well information good show 😅😅
Sir do every periodic table have different type of atom structure ??🤔😕
No absolutely not!
Why your video not get viral
Sir make 2or3videos for one chapter🤔🤔
Sir kya magnesium ko boron ke sath combine kra sakte hai jiski valency 3 hai aur kaise magnesium ki valency toh keval 2 hai plez reply
Very easy method sir thank you sir
Sir! Is structure formation me jo two different atoms kisi bond ke through attach ho rahe hain to uss formed compund ki naming kaise decide hoti h like: Sodium chloride ko chloride sodium kyon ni mention kerte????
nice explanation
Sir jab atom. Ke outermost shell mein123 electron ho toh hum electron transfer krenge kya, and jab 567 ho toh share
Yes
thnk u sir i was really suffering from where this number comes in reaction 💔 thk u so muchh🌹
