Structure of Atom
Heisenberg's state that it is impossible to determine simultaneously, the exact position and exact momentum (or velocity) of an electron. Thus, uncertainty principle is not applicable to stationary electron. Because, when the electron is stationary, its velocity is zero. So we can find out the position of a stationary electron with accuracy.
