Quiz Answer Key and Fun Facts

1. Which gas, finally isolated in 1866, is pale yellow in colour, and is both highly toxic and corrosive?

Answer: fluorine

Early experiments with hydrofluoric acid often ended in tragedy, due to its highly corrosive and toxic nature.

2. Which of the "noble" gases, discovered in 1898, is characterized by its bright orange and green spectral lines?

Answer: krypton

Krypton gas is present in very small concentrations in the air we breathe. It is used in some photographic flash lamps, particularly in the field of high-speed photography.

3. This gas becomes liquid at -196C. It is essential to life, and is a component of all proteins.

Answer: nitrogen

The process known as the "nitrogen cycle", is one of the most important processes in nature, as it sustains the food chain.

4. This gas is the second most abundant element in the universe, and has the lowest melting point of any element.

Answer: helium

Helium is used to fill balloons, as it is lighter than air, and is much safer than hydrogen. The demand for helium is growing rapidly, due to its use in superconductivity applications.

5. Care must be taken when handling this radioactive gas. Long term exposure, especially in smokers, can cause lung cancer.

Answer: radon

In many parts of the world, radon has been detected in people's homes having seeped up from the underlying bedrock. The risk is low for most people, but in smokers exposure to radon is a contributory factor in the development of lung cancer.

6. In nature, this gas is only ever found combined with other elements. In its pure state however, it is fatal if inhaled.

Answer: chlorine

Chlorine gas has been used in several wars as a chemical weapon, and yet one of its greatest benefits, is in the production of safe drinking water.

7. This is the lightest of all the gases, and readily combines with other elements, often explosively!

Answer: hydrogen

Hydrogen has many uses in industry, including rocket fuel, reducing metallic ores, filling balloons, and welding. An important development in technology, is the hydrogen fuel cell.

8. This gas is used with helium in making gas lasers, but is no doubt better known for its use in lighting.

Answer: neon

Neon has over 40 times the refrigerating capacity per unit volume, of liquid helium, and it is less expensive to produce.

9. This gas is used as a protective atmosphere for growing silicon and germanium crystals.

Answer: argon

Argon is commonly used in electric light bulbs, and as an inert gas shield for arc welding and cutting.

10. This gas when combined with hydrogen tends to make things wet, and we would die without it!

Answer: oxygen

Oxygen will combine with most elements, and is present in hundreds of thousands of organic compounds.
