  1. Unit EQ:How is periodic table arranged?What is electron configuration ? Warm-up 10/12/10 • Finish electron configuration for 18 elements, with friend if need help. What do the Bohr models look like? • Test Thursday – PSAT tomorrow • Test review with answers online I MDKJ

  2. Rules for finding Electron configuration of atoms Aufbau principle- electrons occupy orbitals of lowest enrgy 1st Pauli exclusion principle – electrons in the same orbital have to have opposite spins Hund’s Rule – electrons occupy orbitals of the same energy so that the number of electrons with the same spin is as large as possible. What? Explanation-Dealing cards
