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. 00:00 Understanding Molecules and Matter 05:53 Discussion on Organization of Items and Models in Quantum Mechanics 11:48 Analysis of Gold Item and Alpha Particle Interaction 17:44 Understanding the Energy Levels and Orbits of Electrons 23:38 Understanding Electron Distribution in Atomic Nuclei 29:40 Understanding Electron Configuration and Atomic Number 35:35 Understanding Electronic Configuration and Valency in Chemistry 41:33 Understanding Electron Configuration and Atomic Number 47:30 Understanding Atomic Numbers and their Significance
Attendance for those who are here for class 11th chemistry (Atomic structure)😊❤.
I am from class 11 but still I watch this video 📷 for crysta. Clear my basic very useful in chemistry 2

Concept are crystal clear thank you so much 😀☺️
Concept is crystal clear
Thank you mam and concepts are crystal clear 🙏🏻
Mam actually your teaching methods is very simple and outstanding l just hope you will always happy 😍
I have a doubt mam … atomic mass 16 btaya apne oxygen ka vo kha se aya table me likha h vo yaad krna pdega ya phir iska bhi koi formula ya method hota hai
How we got to know about presence of electrons acc to rutherford model?
mam chapter ke notes kaha milega
Concepts hua crystal clear.. Thank you so much ma'am.. Your explanation is really great.. ❤✨

Concepts are crystal clear 👍
Thank you mam for the video do you record ss videos?
Concepts are really crystal clear
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
They way Ur teaching Mam..Absolutely Loved it and Explanation is Awesome
Finally I 👂 listen proton...... 🙌🙄 24:30
Ma'am, I have a doubt about isotope of H. You told that H has only 1 proton in its nucleus and absent neutron. ?????? Please ma'am solve my doubt
Mam really you helped me, I was not idea about atomic structure but my all concepts are clear. thanks a lot! of once again thank you so much! ❤
Concept are crystal clear 👍🏻
The shortest and bestest video I found on yt till now
Concept must be crystal clear ❤️🙏❤️
Mam thank you for making chemistry easy 😊
Best lecture mam, you truly deserve more subscribers at least 1 million and more views
Rutherford's gold foil experiment is performed in 1911 not in 1909....
Clear explanation! 💯
Thank you so much for such good videos , varna school ki teachers to bas notebooks kaam hi karaati hai
I am not perfect in chemistry but after watching this video I thought that I can improve my chemistry by watching your detailed concepts........My concepts are crystals clear I enjoyed this video and learnt alot from it Hoping for best for my tomorrow's exam😊😊😊
Concept crystal clear 🔮💯💯
crystal clear maam
God bless you Didi 🙏🙏🙏 your study method was so simple...... Keep growing 🇮🇳🇮🇳🇮🇳🇮🇳🇮🇳
