If one tries to find the exact location of the electron, say to an uncertainty of only 10−8m, then the uncertainty in velocity would be Δv in
Velocity would be = \(\frac{10^{−4}m^{2}s^{−1}}{10^{−8}m} = 10^4ms^{−1}\)
Which is so large that the classical picture of electrons moving in Bohr orbits cannot hold good. So, it means that the concept of definite orbit (position and momentum of electrons) has to be replaced by concept of probability
