Answer: (c) Ductility

Q2. Which of the following is a non-metal used for water purification?

(a) Sodium
(b) Iodine
(c) Chlorine
(d) Gold

Answer: (c) Chlorine

Q3. Which process can prevent the rusting of iron?

(a) Burning
(b) Melting
(c) Galvanisation
(d) Evaporation

Answer: (c) Galvanisation

Q4. Which of the following is a liquid metal at room temperature?

(a) Iron
(b) Mercury
(c) Aluminium
(d) Zinc

Answer: (b) Mercury

Q5. Which of the following is NOT a property of non-metals?

(a) Poor conductor of heat
(b) Dull appearance
(c) Malleability
(d) Non-sonorous

Answer: (c) Malleability

2. Very Short Answer (VSA).

Q6. What is meant by malleability?

Answer: Malleability is the property of a metal by which it can be beaten into thin sheets without breaking.

Q7. Name one metal and one non-metal that are essential for living organisms.

Answer: Iron (metal) and oxygen (non-metal) are both essential for living organisms.

Q8. Which property of metals is used in making electrical wires?

Answer: The property of ductility, which allows metals to be drawn into wires, is used to make electrical wires.

Q9. Which non-metal is used as an antiseptic?

Answer: Iodine is a non-metal that is used as an antiseptic on wounds.

Q10. State one reason why magnesium ribbon is cleaned with sandpaper before burning in air.

Answer: Magnesium ribbon is cleaned to remove the oxide layer so it can react better with oxygen when burned.

3. Short Answer Questions.

Q11. Why are aluminium and copper suitable for making cooking utensils? Give two reasons.

Answer: Aluminium and copper are both good conductors of heat, allowing food to cook evenly. They are also malleable, so they can be shaped into different utensil forms.

Q12. Explain, with an example, the difference between ductile and brittle substances.

Answer: Ductile substances, like copper, can be drawn into wires without breaking. Brittle substances, like coal or sulfur, break into pieces when hammered and cannot be drawn into wires.

Q13. What is corrosion? Give an example from daily life.

Answer: Corrosion is the gradual deterioration of metals due to reactions with air or water. Rusting of iron railings kept outside is a common example of corrosion in daily life.

Q14. Why are the handles of cooking utensils often made of wood or plastic?

Answer: Wood and plastic are poor conductors of heat, so they prevent heat transfer to our hands. This makes it safe to hold the utensils while cooking hot food.

Q15. What happens when a magnesium ribbon burns in air? What is the nature of the product formed?

Answer: Magnesium ribbon burns with a bright white flame to form magnesium oxide, a white powder. The oxide formed is basic because it turns red litmus paper blue.

Q16. Explain, with reason, why rusting of iron can only occur when both air and water are present.

Answer: Rusting of iron needs both oxygen from air and moisture from water. Experiments show iron does not rust with only dry air or only water; both must be present for rust (brown deposit) to form on iron objects.

Q17. State two differences between metals and non-metals based on their reactions with oxygen.

Answer: Metals react with oxygen to form basic oxides (e.g., magnesium oxide). Non-metals react with oxygen to form acidic oxides (e.g., sulfur dioxide, which forms sulfurous acid when dissolved in water).

4. True or False Questions.

Q18. Metals are generally sonorous in nature.

Answer: True

Q19. Mercury is a metal that remains solid at room temperature.

Answer: False

Q20. Non-metals are good conductors of electricity.

Answer: False

Q21. Malleability and ductility are both present in gold and copper.

Answer: True

Q22. Sulfur forms acidic oxide on reaction with oxygen.

Answer: True

3. Fill in the Blanks Questions.

Q23. The process of depositing a layer of zinc over iron to protect it from rusting is called __________.

Answer: Galvanisation

Q24. The property by which metals can be beaten into thin sheets is called __________.

Answer: Malleability

Q25. __________ is a non-metal essential for respiration in living beings.

Answer: Oxygen

Q26. Non-metals generally react with oxygen to form __________ oxides.

Answer: Acidic

Q27. The ringing sound produced when a metal object is struck is due to its __________ property.

Answer: Sonority
