Hi, I am reading about the quantum model of the atomic structure, and recently encountered the Schrödinger’s model. However I am a bit confused about the nature of the electrons. Can we think of an electron a wave or as a particle when it is inside an atom? I know that in Schrödinger’s theory, an electron always has a probability wave associated with it. So does this fact suggest that an electron is a wave inside an atom? I don’t really understand why we need to have the probability waves at all though. I mean why can we never find exactly where an electron is inside the atom? Is it because of Heisenberg’s uncertainty principle? Thanks in advance!
