Quiz Answer Key and Fun Facts

1. Carbon is the lightest element with a one-letter atomic symbol.

Answer: False

Hydrogen (H) and Boron (B) are lighter.

2. Most of the Martian atmosphere is composed of this carbon compound:

Answer: carbon dioxide

CO2 is less than 1 percent of Earth's atmosphere.

3. What isotope of carbon is analyzed when radioactive dating organic materials?

Answer: Carbon-14

Carbon-14 has a half-life of 5715 years. All living things have a constant ratio of carbon-12:carbon-14. After it dies, the carbon-14 level drops due to radioactive decay. Figuring the ratio left in an organic sample, scientists can determine how many half-life periods the sample has had, and therefore its age.

4. How many carbon compounds have been catalogued?

Answer: 10,000,000

5. What does 'carbon' mean?

Answer: charcoal

From the Latin carbo.
