1-2) The Atomic Hotel The Atomic Hotel is a special hotel designed for electrons. The hotel has a strict policy called the Aufbau principle that states "ground" floors must be filled first and in order. It costs more to get rooms on higher floors. In the atomic world energy is money so "excited" electrons get I. rooms on higher floors, thus the exception to hotel policy. Looking back through the old guest logs the following layouts can be sketched. Determine which electrons had more "money". Label those electrons as excited. |1 1|| 1 |1L||1L||1L May 23, 1998 June 19, 1999 September 10, 1991 C A B II. Another policy that the hotel enforces is called the Pauli Exclusion Principle. It was determined in 1925 that electrons can occupy the same room, but only if they have opposite spins so they do not interfere with one another. Which electrons below did not follow the Pauli exclusion principle? 1 1 1 1 1 1 11 1 1 |1. 1L 1 1 1 1 11 1 1 1 1 1 1| 1L 1L 1L April 2, 1995 December 1, 2000 July 4,…
