According to Heisenberg’s uncertainty principle ,it is impossible to know the electron’s velocity and its position simultaneously.The exact position of the electron at any given time cannot be known.Therefore, it is impossible to obtain a photographic picture of the atom like we could of a busy street. Electrons are more like fast-moving moss mosquitoes in a swarm that cannot be phtographed without appearing blurred. The unceraitainty about their position persists even in the photograph.An alternative picture of the swarm can be obtained by describing the area where the mosquitoes tend to be concentrated and the factors that determine their preference for certain locations, and that’s the best wa can do.
