Structure of the Atom Class 9 Science | One Shot | Chapter 4 | Chemistry NCERT CBSE

[@shreya2976]

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.

Hi army

[@manojkumarmandal9258]

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

[@Loneishu729]

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 ❤

[@mbsbking8372]

19:15 but mam in evergreen book it is clearly written that he would have got different observation as other metals are not so malleable
And most atoms have been rebound
Please tell mam
Which one is right 😊😊
