| Room 12. Great job! Next clue for Room 12: After escaping from the last room you materialize in a room made of a solid substance. Mendeleev’s image appears in front of you and says, “This element is the basic unit for all living things.” | Room12-Clue1
| Clue 2 - “Without it, jewelers would go broke, gas stations would go out of business, and every breath you exhale would be incomplete.” | Room12-Clue2
| Clue 3- "This element is used in radioactive dating." | Room12-Clue3
| Clue 4 - “The element has 6 neutrons and an atomic mass of 12.” | Room12-Clue4
| Room 13. Great job! Next clue for Room 13: The next room you enter is filled with a gas. The gas is colorless and nonreactice. | Room13-Clue1
| Clue 2 - Mendeleev appears, telling you, “When electricity is run through it, the gas emits a brilliant orange-red light when contained in a discharge tube.” | Room13-Clue2
| Clue 3 – “Las Vegas wouldn’t be the same without this element.” | Room13-Clue3
| Clue 4 – “This element has 10 electrons and 10 neutrons.” | Room13-clue4
| Room 14. Great job! Next clue for Room 14: This room is made of a light gray metal. Again, the image of Mendeleev speaks, “This element is so strong, hard, and elastic that it is used in alloys to reinforce other metals. Its melting point is nearly 1300oC.” | Room14-Clue1
| Clue 2 – It is part of the Alkaline Earth Metals Family. | Room14-Clue2
| Clue 3 – It reacts by losing two electrons. | Room14-Clue3
| Clue 4 - It has 4 protons. | Room14-Clue4
| Room 15. Great job! Next clue for Room 15: The next room is made of a hard, black, shiny material and then suddenly it changes to a brown powder. The old chemist appears and says “This does not conduct heat or electricity well. It can withstand really high heats and is used in making scientific glassware." | Room15-Clue1
| Clue 2 - The holograph of the chemist tells you the atoms of this element have 2 electron shells. | Room15-Clue2
| Clue 3 – This element is a metalloid on the second floor of the castle. | Room15-Clue3
| Clue 4 - This element has a rounded atomic mass of 11 and 6 neutrons. | Room15-Clue4
| Room 16. Great job! Next clue for Room 16: The sixteenth room you enter is made of a greenish-yellow gas. The image tells you, “Be very careful, this element is the most reactive of the nonmetals.” | Room16-Clue1
