Class 10 Science Chapter 3 Extra Question Answers
Why are aluminium and copper metals used for making cooking vessels?
Aluminium and copper metals are good conductor of heat. When exposed to air, these develop a layer of oxide. This makes it resistant to further corrosion.
Why is sodium kept immersed in kerosene oil?
Sodium is very reactive. If kept exposed to air, it catches fire.
Distinguish between calcinations and roasting.
(i) The ore is heated is absence of air.
(ii) It is used for carbonate ores.
(i) The ore is heated in the presence of air.
(ii) It is used for sulphide ores.
Ionic compounds have high melting point. Why? Give reason in support your answer.
In iconic compounds, ions are joined together due to powerful electrostatic forces, therefore, considerable energy is required to separate these ions and break the lattice. Thus ionic compounds have high melting points.
Generally, Ionic compounds are hard crystalline solids. Why?
There are solids due to strong force of attraction between oppositely charged ions resulting in the formation of hard crystalline lattice.
What are alloys?
An alloy is a homogeneous mixture of two or more metals, or a metals and a non-metal. It is prepared by first melting the main metal, and then dissolving the required amount of other metals or non-metals. This mixture is then cooled to form an alloy of a given composition.
What is meant by metallurgy?
Metallurgy involves various processes starting with the treatment of ore to getting metals in the pure form.

Important Questions on 10th Science Chapter 3
Name two metals which will displace hydrogen from dilute acids, and two metals which will not.
Metals that are more reactive than hydrogen displace it from dilute acids. For example: sodium and potassium. Metals that are less reactive than hydrogen do not displace it. For example: copper and silver.
What are the two important ways to prevent the rusting of iron?
Oiling, greasing, or painting: By applying oil, grease, or paint, the surface becomes water proof and the moisture and oxygen present in the air cannot come into direct contact with iron. Hence, rusting is prevented. Galvanisation: An iron article is coated with a layer of zinc metal, which prevents the iron to come in contact with oxygen and moisture. Hence, rusting is prevented.
Platinum, gold and silver are used to make jewellery. Why?
Platinum, gold, and silver are used to make jewellery because they are very lustrous. Also, they are very less reactive and do not corrode easily.
Why are Sodium, potassium and lithium stored under oil?
Sodium, potassium, and lithium are very reactive metals and react very vigorously with air as well as water. Therefore, they are kept immersed in kerosene oil in order to prevent their contact with air and moisture.
Aluminium is a highly reactive metal, yet it is used to make utensils for cooking. Why?
Though aluminium is a highly reactive metal, it is resistant to corrosion. This is because aluminium reacts with oxygen present in air to form a thin layer of aluminium oxide. This oxide layer is very stable and prevents further reaction of aluminium with oxygen. Also, it is light in weight and a good conductor of heat. Hence, it is used to make cooking utensils.
Carbonate and Sulphide ores are usually converted into oxides during the process of extraction. Why?
Carbonate and sulphide ores are usually converted into oxides during the process of extraction because metals can be easily extracted from their oxides rather than from their carbonates and sulphides.
How is an ore different from a mineral?
“all ores are minerals but all minerals are not ores”. Justify the statement with examples.
The metals found in nature in combined state are called minerals. If some minerals contain a very high percentage of a particular metal and the metals can be profitably and economically extracted, then it is called an ore.
Atmospheric air always contains moisture. Then, how can you protect iron articles from the affect of atmosphere?
Iron articles can be protected from the effect of atmosphere by painting, oiling and greasing. This gives temporary protection to iron articles. For long time protection, galvanising or chrome plating are quite useful.

NCERT Class 10 Science Chapter 3, titled Metals and Non-Metals, is important from an exam perspective for several reasons. Questions related to metals and non-metals are an essential part of the Class 10 Science curriculum and typically carry a significant weightage in the board exams. Devoting sufficient time and effort to this chapter can help students score well in the science paper. This chapter introduces fundamental concepts related to the properties, classification, and chemical behavior of metals and non-metals. A strong understanding of these concepts is crucial as they serve as the foundation for more advanced chemistry topics in higher classes.
What determines the reactivity of metals?
When metals react, they lose electrons to form positive ions. Such metals which can lose electrons easily to form positive ions when reacted with other substances, are reactive metals. On the other hand, if a metal loses electrons less rapidly to form positive ions, it will reacts slowly with other substances. Such a metal will be less reactive. For example, sodium atom is a very reactive metals because it readily loses one electron, forms a positive ion which then combines with other substances. On the other hand, lead atom loses electrons with difficulty to form positive ions, so lead metal is less reactive.
The Chapter 3 of 10th Science includes numerical problems related to chemical reactions and properties of metals and non-metals. These problems assess students’ problem-solving skills and their ability to apply concepts in real-world scenarios. The chapter covers various chemical reactions involving metals, such as reactions with oxygen, water, and acids. Understanding these reactions and being able to balance chemical equations is important for answering questions accurately. Knowledge of the properties and uses of metals and non-metals in daily life and industry is tested in the exams. Students may be asked to explain the practical applications of specific materials.
Questions related to displacement reactions, which are a key concept in this chapter, often appear in the exams. Students need to understand the reactivity series and how it predicts the outcome of displacement reactions. The chapter discusses the environmental impact of various metals and non-metals, including issues related to mining and pollution. These topics are relevant and may be tested in the context of environmental science. Corrosion is a critical concept covered in the chapter 3 of 10th Science.
