1. Electrons orbit the nucleus. They are held in orbit by an electrostatic force.
2. Electrons can only be in certain, permitted orbits and an electron does not emit radiation when it is in one of these orbits.
3. An electron only emits radiation when it "falls" from a higher energy state to a lower state.
4. The radii of the allowed orbits are also quantized - each energy state has a specific radius proportional to h/2Ï€.
5.Angular momentum of electron will be mvr = nh/2Ï€,n is principle quantum no.

Where can Koch's postulates be found?
Koch's postulates can be found in all organisms. This is taught is science.
How can we contact Koch's postulates?
You cannot not contact Koch's postulates. This is found only in plants.
What are two postulates that is not true about atom?
If they are known not to be true then they are no longer postulates but discarded theories.
Why is it necessary to use postulates in geometry?
Postulates are statements that prove a fact. An example would be that 2 points create a line segment. You usually use postulates in proofs.
Do axioms and postulates require proof?
No. Axioms and postulates are statements that we accept as true without proof.
Are postulates excepted as true without proof?
Yes, postulates are accepted without proof and do not have counterexamples.
Why was bohrs model accepted widely?
yep- pretty sure
