Chapter 7 Quantum Theory and the Electronic Structure of Atoms
... An interesting question for your students is to ask them to indicate what the maximum number of electrons a 3p orbital can have. They may very well indicate six, but the correct answer is two. (That is the maximum for all orbitals). The logic of answering six is that there are six electrons that can ...

Quantum mechanical description of identical particles
... The fact that particles can be identical has important consequences in statistical mechanics. Calculations in statistical mechanics rely on probabilistic arguments, which are sensitive to whether or not the objects being studied are identical. As a result, identical particles exhibit markedly differ ...

Testing Lorentz Invariance in High-Energy
