Quiz Answer Key and Fun Facts

1. Which of the following metals burns in both oxygen and nitrogen?

Answer: Zirconium

Zirconium is a metal that burns in both nitrogen and oxygen. Its atomic number is 40. This metal has the special property of absorbing neutrons so it is used in nuclear reactors.

2. Which is the lightest element to be found in nature?

Answer: Hydrogen

Hydrogen is the lightest element to be found in nature. Its atomic number is 1 and it has no neutrons in it.

3. Which is the lightest metallic element to be found in nature?

Answer: Lithium

Lithium is the lightest metallic element to be found in nature. Its atomic number is 3. Lithium is generally used in mobile batteries.

4. Which is the most reactive metallic element found in nature?

Answer: Cesium

Cesium is the most reactive metallic element to be found in nature. It is placed at the top of the reactivity series, followed by francium and potassium. Cesium has a very low melting point.

5. Which is the most reactive non metallic element to be found in nature?

Answer: Fluorine

Fluorine is the most reactive non metal to be found in nature. Its atomic number is 9. It is generally found in a gaseous state.

6. Which non metal exists in a liquid state?

Answer: Bromine

Bromine is the only non metal to exist in a liquid state. It is also found in gaseous state. Its atomic number is 35.

7. Which of the following gases is mixed with oxygen for breathing during scuba diving?

Answer: Helium

Helium gas is mixed with oxygen for breathing during scuba diving. Oxygen is used for breathing while helium makes the cylinder lighter to carry.

8. Francium is a radioactive metal.

Answer: True

Yes, francium is a radioactive metal. It generally exists in liquid state. Its atomic number is 87.

9. Which of the following is used as a coolant in nuclear reactors?

Answer: All of these

In a nuclear reactor water as well as any molten metal can be used as a coolant. Coolants generally control the temperature emitted during reaction.

10. Diamond is an allotrope of lead.

Answer: False

Diamond is an allotrope of carbon, not of lead. A diamond is the hardest natural substance known on this Earth.
