Who Is Here To Clear Basics Of Atom For Class 11😅😊

[shreya]

The video discusses the structure of atoms and molecules, including electronic configuration, valency, and atomic number. It also explores the behavior and interaction of alpha particles within a gold item, as well as the electron distribution and behavior in atomic nuclei. The limitations and possibilities of building a home in a specific colony are also explained.

Thanks mam I am in 11th class but my basic not clear than I see your 11th class video and you recommend this 9th chapter and I understand that thank you so much mam

[Studentkaksh]

You are amazing mam, loved your content, you will get 1 crore subscribers one day😊😊😊

[Singwithstudy-kfgg]

Attendance for those who are here for class 11th chemistry (Atomic structure)😊❤.

[davinderjeetkaur]

Best teacher in the world for science
And the concepts are crystal clear 😊😄❣️

[surendersaroha]

Mam thank you for all the hard work for us you and your team are blessed with animation skills may your channel grow even more your educating skills are awesome😊😊😊

[manojkumarmandal]

বলছিলাম যে পরামুর গঠন A^X^Z দ্বারা যদি A কে পারমানবিক সংখ্যা বোঝাই
তাহলে ইলেক্ট্রন গঠন -1^e^0 দ্বারা এর পারমানবিক সংখ্যা _1।এটি কিভাবে সম্ভব।কারো পারমানবিক সংখ্যা নেগেটিভ ।।।How is it possible?pls ans me

[nadiradiya]

I am from Bangladesh but I always enjoy your classes ❤

[Akhileshyadav-tcqr]

Mam you are the one of the best teacher in the whole universe "Thank you so much mam❤❤"
Concept hua crystal clear

[haneefkhan]

After see this video
I realized chemistry is the best subject
Thanku for your explanation Mam
My concept are crystal clear❤

[rakheeteothia]

The class was very good as full effort was given by the teacher. Thank you.

[arohi_]

Me to ma'am ke bolne pr hi yha aayi hoon😂😂

[Studentkaksh]

Best lecture mam, you truly deserve more subscribers at least 1 million and more views

[fuvg]

Mam actually your teaching methods is very simple and outstanding l just hope you will always happy 😍

[neetutiwari]

MAHARISHI KANAD of India has first discrib atom ( Dalton se dhy hajar sal pahle )🇮🇳💯💪

[nivedithatn]

Super explanation with animation thank you mam

[Loneishu]

Oh i can't understand anything clearly 😢 but to understand i always come here to see your videos mam and allahumdulilah it's very helpful tysm ❤
