How an electron transition from lower energy state to higher energy state in hydrogen atom emits a photon?

What is your level of knowledge? There are many possible answers to this question, but unless you know something about quantum field theory, it will probably stay at the level of "something is moving, so it emits radiation".
 
There is noway this can happen...where did you read that? the photon would need to have negative energy... except for if you mean absorb?
 
Oh wait, lower to higher? No, that does not work. I read "higher to lower", as that is a common question.

Thread 'Quantum behaviour of an electron around a positively charged sphere'

If we release an electron around a positively charged sphere, the initial state of electron is a linear combination of Hydrogen-like states. According to quantum mechanics, evolution of time would not change this initial state because the potential is time independent. However, classically we expect the electron to collide with the sphere. So, it seems that the quantum and classics predict different behaviours!
