Understanding Bohr's Atom: his postulates and the limitations

In this video, I discuss the postulates of Bohr's atom, how it solves the problem of Rutherford's model and how at the same time explains the lines is spectral analysis, including the Balmer lines.

THIS IS ONE OF THE MOST INCREDIBLE VIDEOS IVE EVER SEEN YOU SAVED MY GRADUATION EXAM!!! THANK YOU SO MUCH. nobody ever explains the postulates so in-depth (and NO ONE EVER EXPLAINS WHAT BLUDDY QUANTISED MEANS!)

[mariat]

you are amazing!!! Thank you so much for making these videos. Please keep up the great work - they're a fantastic resource and are helping tons of students!

Is there any explanation behind this postulate on why electrons in stable orbits do not radiate? I am trying to understand this instead of just remembering the postulates without knowing why.

[russhouldin]

Why is the whole structure stable? Coulomb's laws says their is always attraction between a positive and negative charge proportional the square of the distance between them. As that distance gets smaller the force gets bigger. Why don't electrons in the first shell get attracted to the nucleus and become absorbed? Is it the centrifugal force of an "orbiting" electron? What other force could there be? If it is centrifugal force how does that square with the conception of the electron "cloud"? Further why does this force not figure in the Schrodinger equation which only includes the Coulomb force? Thanks.

Sir I have a question plz reply why does the angular momentum of an electron increase with increase in radius in the bohr model as it should decrease generally because the velocity is decreasing ...

[mikeoxlong]

does the electron actually change orbit when absorbing a discrete amount of energy ? Why cant the model explain multi electron spectra?

[panaden]

Thank u Sir.for clearly & practically explaining confusing & vaguely understood subject.

[tripatdeepsingh]

isn't bohr's second postulate to do with electron transitions, whereas his third is to do with angular momentum?

Whay do you call necleus a "nucilus"?

[maynardjohnson]

Have you noticed that you say "he" instead of "here".
