I was wondering why does an electron not just bumps into the nucleus? they explained me, but i don´t understand. I know that there are many more electrons moving around and that they could repel each other, but how is it with an atom with only one electron? Has it to do with the speed of an electron?

paulis exclusion pricipe does not allow this
also the speed of electron is same greater than speed of light which contradicts einstien words that nothing can be faster than light
also there is no angular momentum of electron which supports principle quantum no of nucleus

in an atom, energies of each orbit is quantized i.e they can hv only certain amt of energies & not any arbitrary amt of energy. so, in an atom of 1 electron, the first orbit can hv only a certain amt of energy(i cant recall the xact amt). it can only bump into the nucleus if it has lower energy than that which is not possible cos of above reasons. i hope it makes sense!!!

Men have been taught that it is a virtue to agree with others. But the creator is the man who disagrees. Men have been taught that it is a virtue to swim with the current. But the creator is the man who goes against the current. Men have been taught that it is a virtue to stand together. But the creator is the man who stands alone. |

Use heisenberg's uncertainity principle. Radius of nucleus if u put as uncertainity in position , uncertainity in speed comes out to be more than speed of light. THis is not possible. hence electron cannot bump into nucleus........does that answer ur question?
