From high school chemistry I learnt that orbital is the region where probability of finding an electron is high. (Probability, since electron has no well defined location.) Different types of orbitals have different shape of region. I also learnt that different orbitals of the same shell may undergo hybridisation, becoming hybridised orbitals which have different shape of region. Why does the region of the hybridised orbitals different from the original orbitals? Is it related to Uncertainity in Quantum Physics?
