CHEM 1062 Chapter Notes - Chapter 8: Inner Core, Magnetic Quantum Number, Paramagnetism
Document Summary
Chapter 8 electron configuration and chemical periodicity electron configuration = the distribution of electrons within the levels and sublevels of its atoms. Schrodinger equation give good approximate solutions, only exact for hydrogen. Three quantum numbers: n, l, ml describe size (energy), shape and orientation of an atomic orbital. Spin is the last number: ms which is a property of the electron not the orbital. Ms can be positive or negative . Eech electron in an atom is described completely by these 4 quantum numbers. Principal quantum number is n; can be a positive integer. Angular momentum is l, can be integers 0 to n-1. L values 0,1,2,3 correspond to s,p,d,f orbitals respectively. Magnetic quantum number is ml and can be integers -l to 0 to +1. Spin quantum number is ms, can be + or - . Exclusion principle is that an atomic orbital can hold a maximum of 2 electrons and they must have opposing spins.
