# Why doesn't a electron stops to orbit the nucleus? [duplicate]

We always learned in the high school that electrons always orbit the nucleus (I read about, and it seems that this theory is obsolete: electrons doesn't orbit the nucleus), but I am asking my self now:

How does the electron not stops?

Where does the energy to orbit comes from?

• @IanF1 Unlike planets electrons radiate energy very intensely when accelerating. It was estimated that they would fall into the nuclei and atoms would collapse in $10^{-12}$ seconds. Bohr's "explanation" for why this doesn't happen was that electrons just don't radiate when they are in some specific orbits, just cause. But it worked physics.weber.edu/carroll/honors/failures.htm – Conifold Oct 11 '16 at 20:12
