Drawbacks of rutherford atomic model
1) Electrons would revolve and thus undergo acceleration,during acceleration they would radiate energy
2) Electons would then lose energy and fall into the nucleus
3)If this were so, they would be unstable but as we know today atoms are quite stable.
Postulates of Bohrs atomic model:-
1) Only special kinds of atoms are allowed in atom known as discrete orbits.
2) Electrons while revolving in these orbits , they would not radiate energy.
Thank YOU So Much Ma'am.....u helped me so much clearing doubts from this Ch...
Kiska kiska kaal he exam hai ajj pw leke baitha hai batao
Mare hai
I wish everyone will get 100% in 9th class

🔥 session is clear mam
He called this region of the atom as a nucleus. Rutherford's model proposed that the negatively charged electrons surround the nucleus of an atom. He also claimed that the electrons surrounding the nucleus revolve around it with very high speed in circular paths. He named these circular paths as orbits.
This is Bohr's Model of an atom
Rutherford drawback was - He said that electrons moves in a circular path around the nucleus and as we all know that every body which moves in a circluar path will go through under accleration so electrons will also go through under acclerstion and will rediate (losse) energy because of which it will fall on nucleus and destroy it by which matter will become unstable
Well yes, Rutherford did state that electrons revolve around the nucleus in circular orbits..
However, since electrons are charged species (negatively charged) and according to Maxwells electromagnetic theory, any particle undergoing circular motion will accelerate. Hence, it will radiate energy..,hence, based on similar principles, if electron was to revolve around the nucleus without any specifications, which wasn't specified by Rutherford, would eventually lose energy and fall into the nucleus.
However, in 1913, Bohr did come up with an atomic model to overcome the shortcomings of Rutherfords atomic model.
I just can't understand why this type of amazing teachers we don't get in our school
a-3,b-4,c-1,d-2,e-5,f-6
atomic number is defined as the total number of proton present in nucleus of an atom
I'm having my exam tmrw and this was the only chapter I found it difficult.. TQSM :)

Kon kon ye video 11th me dekh raha hai😅😅😅😅
Gawar h tum
may 9th may dhk rahi hu
Amu ke liye dekh rha hu bhai😂😂
Here the thala is
..
Main dikh rhe hu
electron revolve in orbit and electron lose charge and electron end in nuclues
Perfect example of beauty with brain❤
1:18:17
1 only special orbits called discrete orbits are allowed inside the atom
2 why revolving in these discrete orbits atoms will not radiate energy
Legends are watching after exams 😅
Thank you mam for this video it's very helpful ❤
Thank u Didi😊😊😊

op explanaion mam ( * - * )
🔵 Thankyou so much for a very interesting lecture ❤
Currently I'm in about to go in 9th standard and already done 5 chapters of science
(School jaa ke sbse tezz bn jaaungaa😅)
20 ko kis kis ka paper khatam ho jayega.......!!!!
Are you from KV (bhopal region)

1:17:52 when electrons move in a circular orbit they undergo acceleration and radiate energy, that means they fall into the nucleus and hence the nucleus will be destroyed and atom will also be destroyed. He can't explain the stability of atoms.
No they move in path but they are stable
Mam aapne ek chiz nii btaya eesme..kii experiment ke wqt cathode wale me cathode electrode perforated rkha gya tha aur anode wale me anode electrode ko perforated rkha gya tha tb hi toh electricity pass krane pr udhar se aane wali rays yha perforated se touch hui and dusra ray nikla and lastly piche fluroscent screen pe glow hua...
😮Kon kon 11 main dekh raha hai bahot hogaya. 😮😮😮😮 ab batao 4 class main kon kon dekh raha h😅😅😅😅
A-Z=no. of neutron so, 31-15= 16 so, no.of neutron=16
Thanku maam....♥️
Hamari aise chemistry teacher ho to kabhi class miss na kare 😏
Best chemistry teacher is Sanya ma'am ❤ who agrees?
I don't
Just go and watch his lectures
Mam is alpha particle are he²+ ions ???
Thank you so much.. ❤
