- Your major task is to fill rooms in your hotel. The funny shape of your hotel is to accommodate the habits of the hogs. The penthouse is on the first floor and the less desirable rooms are on the top floor. You must fill up your hotel keeping the following rules in mind:
1) Hogs are lazy!

2) Hogs can’t stand each other except when rule #1 forces the

to put up with each other.

3) If hogs are in the same room they will face in opposite directions.

4) They stink, so you can’t put more than two hogs in each room.

Important Definitions shape of your hotel is to accommodate the habits of the hogs. The penthouse is on the first floor and the less desirable rooms are on the top floor. You must fill up your hotel keeping the following rules in mind:

- Principal Energy Levels – are assigned values in order of increasing energy: n=1,2,3,4. The greater the number the further away from the nucleus. As you move closer to the nucleus the energy of an electron decreases.
- Ground State – lowest energy state of an atom
- Atomic orbitals – orbitals have different shapes and are denoted by s, p, d, f

Rules for filling oribitals shape of your hotel is to accommodate the habits of the hogs. The penthouse is on the first floor and the less desirable rooms are on the top floor. You must fill up your hotel keeping the following rules in mind:

- Pauli Exclusion Principle – an orbital may contain no more than two electrons.
- Aufbau Principle – electrons occupy the lowest energy orbital available.
- Hund’s Rule – when you have several orbitals of the same energy place one electron in each orbital before doubling up.
