Quiz Answer Key and Fun Facts

1. Which non-metal has the ability to conduct electricity?

Answer: Graphite

Graphite is the only non-metal which can conduct electricity because it has free moving electrons. Graphite is used as an electrode in electric cells and to make leads of pencils.

2. Which of the following chemical solutions has the ability to dissolve gold?

Answer: Aqua regia

Aqua regia is a freshly prepared mixture of concentrated nitric acid and concentrated hydrochloric acid in the ratio 1:3.

This chemical has the ability to dissolve even gold. It is a highly corrosive and fuming liquid.

3. Which of the following elements is neither a metal nor a non-metal?

Answer: Tellurium

The elements which are neither a metal nor a non-metal are termed as metalloids. Tellurium is a metalloid. Metalloids shows the property of both metals ans non-metals. Radon is a non-metal while antimony and yttrium are metals.

4. Which expensive element is the most ductile metal?

Answer: Gold

Ductility is the property of an element in which any element can be converted into thin wires. Gold is the most ductile metal. 2 km of long wires can be drawn from 1 gm of gold.

5. During galvanization, which element is coated on iron to protect it from rusting?

Answer: Zinc

Galvanization is a process in which a thin layer of zinc is coated on iron to protect it from rusting. As zinc is more reactive than iron it protects it from further oxidation or rusting.

6. Which solid non-metal is normally kept under water?

Answer: White phosphorus

White phosphorus is kept under water because it reacts with oxygen in air vigorously and start burning. So under water it remains away from atmospheric air.

7. Which of the following is not an ore of magnesium?

Answer: Siderite

Dolomite, carnallite and Epsom salt are ores of magnesium while siderite is an ore of iron.

8. Sodium is a metal?

Answer: True

Yes, sodium is a metal. It is a highly reactive and soft metal. It is so soft that it can be easily cut with a knife. It reacts with air and water and starts burning. Consequently, it is stored in kerosene.

9. Which non-metal reacts with concentrated nitric acid?

Answer: Sulphur

Generally, non-metals do not react with acids but sulphur and phosphorus are two non-metals which react with concentrated nitric acid and release nitrogen gas.

10. Rubies and sapphires are both varieties of which mineral?

Answer: Corundum

Rubies and sapphires are both varieties of corundum, which is a crystalline form of aluminium oxide with traces of iron and chromium. It belongs to the hematite group where metals which also includes metals such as iron.
