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".

His Dalton's Atomic Theory ideas form the atomic theory of matter. Here are his ideas. • All elements are composed (made up) of atoms. It is impossible to divide or destroy an atom. • All atoms of the same elements are alike. (One Atoms of element X Atoms of ement Y Compound of elemeite XandY atom of oxygenis like another atom of oxygen.) • Atoms of different elements are different. (An atom of oxygen is different from an atom of hydrogen.) • Atoms of different elements combine to form a compound. These atoms have to be in definite whole number ratios.
