Document Summary

Chem 101 - lecture 6 - multielectron atoms. 2 you are expected to sketch/interpret s,p,d orbitals. You must sketch or interpret a plot of a simplified wave function n. The first 3 quantum numbers refer to atomic orbital. Filling order is known as electron configuration (will be covered in online lecture) When a beam of hydrogen atoms passes through a nonuniform magnetic field, the beam splits into 2 beams. This demonstrates that an electron has magnetic properties. The fourth quantum number is known as spin quantum number denoted as ms. The values of ms can be - or + . Electrons with the same same spin are said to have parallel spin. Electrons with different spins are said to have opposite spins. No electrons in an atom can have the same four quantum numbers. There can only be 2 electrons in an atomic orbital. Electrons within the same atomic orbital must have opposite spins.
