      Electrons exhibit both wave and particle behaviors. (de Broglie) The absolute location of an electron is impossible to determine – its location and velocity cannot be determined at the same time. (Heisenberg) The electrons travel in orbitals that have characteristic sizes, shapes, and energies, but do not describe how the electrons move ...
