| 1. | The chemistry of heavier noble gases, krypton and xenon, are well established.
|
| 2. | Noble gases are typically highly unreactive except when under particular extreme conditions.
|
| 3. | The noble gases are colorless, odorless, tasteless, and nonflammable under standard conditions.
|
| 4. | Noble gases are considered stable since they contain the desired eight electrons.
|
| 5. | Other separations include noble gases, N 2, O 2, freon and formaldehyde.
|
| 6. | Krypton, like the other noble gases, is used in lighting and photography.
|
| 7. | Neon and other noble gases have characteristic emission frequencies ( colors ).
|
| 8. | The heavier noble gases have more electron shells than the lighter ones.
|
| 9. | Can noble gases form compounds under extreme conditions of temprature and pressure?
|
| 10. | All of the noble gases have full outer shells with eight electrons.
