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.
Kiske exams 16 march tk h??😢

Thanks mam you are amazing 😍 because your way of teaching is also amazing 😀🤩😊
Thank YOU So Much Ma'am.....u helped me so much clearing doubts from this Ch...
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.

Currently I'm in about to go in 9th standard and already done 5 chapters of science
(School jaa ke sbse tezz bn jaaungaa😅)
atomic number is defined as the total number of proton present in nucleus of an atom
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.
Thanku so much mam❤. Your every oneshot video helped me a lot to get prepare for my exams🎉 once again thanku so much mam❤😊
Thank you mam for your wonderful explanation....
i understood everything
🔥🔥🔥
Revised all chemistry in a month thank you.mam ❤
Thankyou so much mam. 😊❤😊
electron revolve in orbit and electron lose charge and electron end in nuclues
a-3,b-4,c-1,d-2,e-5,f-6
7:36 mam the anode rays were not given by anode they were made from the ionisation of gas present in the tube the ionisation occured due to cathode rays
I'm having my exam tmrw and this was the only chapter I found it difficult.. TQSM :)
Same here
Same
Same for finals
Lagta hai tune Tissue nahi padha😅

Tomorrow is my science exam .... 😊❤🎉
Such an energytic teacher
Energy vibes😊
A-Z=no. of neutron so, 31-15= 16 so, no.of neutron=16
Thx u ma'am for this video.

1 only special orbits called discrete orbits are allowed inside the atom
2 why revolving in these discrete orbits atoms will not radiate energy
Crystal clear mam!!!😇
mam such a beautiful explaination i ever seen thanks mam😄
Perfect example of beauty with brain❤
🔥 session is clear mam
Wow❤ nice explanation
Who is the❤❤ really lover of pw and his teacher like more or more 😊
atomic no. = no.of proton
I love you mam. God bless you 😇❤
Q2:- c) nucleus in atom
Thanks mam
I understand everything very well...once again ty mam🥰
