Bohr's Model of an Atom - Class 9 Tutorial

In 1913 Bohr proposed his quantized shell model of the atom to explain how electrons can have stable orbits around the nucleus. The motion of the electrons in the Rutherford model was unstable because, according to classical mechanics and electromagnetic theory, any charged particle moving on a curved path emits electromagnetic radiation; thus, the electrons would lose energy and spiral into the nucleus. To remedy the stability problem, Bohr modified the Rutherford model by requiring that the electrons move in orbits of fixed size and energy.
The energy of an electron depends on the size of the orbit and is lower for smaller orbits. Radiation can occur only when the electron jumps from one orbit to another. The atom will be completely stable in the state with the smallest orbit, since there is no orbit of lower energy into which the electron can jump.

we study these in grade 11? which country is it to have it on grade 9, ?

Amritacreate does excellent job in education sector. i love all the videos. they uploads and explain wonderful tutorials.i found it the best at Youtube. congratulations to team

[tanishqas]

These videos are great....pls do much more videos like these

[sakirwahid]

I m made for science and I liked the way you represented it thanks

[nics_]

So useful! I'm going to use this video in my report. With your credits. Thank you!

IT SAYS THAT MAXIMUM NUMBER OF ELECTRON THAT OUTERMOST ORBIT CAN HOLD IS JUST 8 !!?? IT CONFUSES ME ... WHAT DOES IT MEANS ..????

[aymannoah]

Thank you so much for helping me with this, actually I would not understand without watching this video📝📝📝

[saburstube]

this is very useful video, I can explain much better to my student by saw this video....

thanks for make those type of video

[akmt]

upload more about shell or energy levels

[Swammy]

2:58 it says Niel's Bohr, btw its Niels

[vilasdhande]

why orbit close to nucleus have. minimum energy...

[asharma]

its actually BOHR NOT BHOR

BTW the video is very helping... Thanks

[prabirmollick]

This is wonderful to teach the student.

[hemapriya]

this is very nice concept really very help full for all students

[vijayachaudhari]

Thanks for the video.Please upload more videos like this

[sohamemon]

can any body tell in which direction they are moving anticlock or clockwise?

[jaswantgarcha]

because of u I have got 2 nd position in my class

[archanakesharwani]

Yet a lot of doubt what is basic difference between orbit and shell

[balkrishnanayak]

Is there any abbreviation of K L M N ?

[kundanpachpande]

shells are denoted by letters' k l m n ' then what is the letter for 5th shell ?
