Electrons move as waves Interference – Dr Quantum Delocalized – STM images of Fe or Cu atoms Uncertainty Principle: You can’t know the position and momentum of an electron at the same time. (∆x∆p >= h /2) ( Smaller orbital has higher kinetic energy (∆x∆p) Energy of Electron Potential Energy o Nuclear charge o Radius o e- - e- repulsion Kinetic Energy o Purely quantum! o Higher for small orbitals. Size of orbital – n – 1, 2, 3 …. Shape of orbital – l – 0, 1 ,2, …. n-1
