CHM110H5 Chapter Notes - Chapter 3.6: Pauli Exclusion Principle, Atomic Orbital
Document Summary
Electron clouds (orbitals: although we cannot know how the electron travels around the nucleus we can know where it spends the majority of its time (thus, we can know position but not trajectory). The probability of finding an electron around a nucleus can be calculated. Relative probability is indicated by a series of dots, indicating the electron cloud : 90%electronprobability/cloud for 1s orbital (notice higher probability toward the centre) Summary: p orbitals and d orbitals p orbitals look like a dumbell with 3 orientations: px, py, pz ( p sub z ). Four of the d orbitals resemble two dumbells in a clover shape. The last d orbital resembles a p orbital with a donut wrapped around the middle. The pauli exclusion principle states that each electron (waveform) has a unique set of quantum numbers: no two electrons can have the same values for all quantum numbers. Kind a like how each apartment in a building has only one address.
