NCERT Solutions for Class 10 Science Chapter 3 Topics

3.1 Physical Properties: In the periodic table, there are two broad classes of elements: those classified as metals and those classified as non-metals. These two classes of elements have different physical properties.

Following subtopics will be discussed in the section 3.1: 

       3.1.1 Metals

       3.1.2 Non-metals

3.2 Chemical Properties of Metals: Metals have a wide range of chemical properties because they lose electrons and form cations (positive ions) during chemical reactions.

Following subtopics will be discussed in the section 3.2:

       3.2.1 What happens when metals are burnt in air?

       3.2.2 What happens when metals react with water?

       3.2.3 What happens when metals react with acids?

       3.2.4 How do metals react with solutions of other metal salts?

       3.2.5 The reactivity series

3.3 How do metals and Non-metals react?: Metals and Non-metals may interact with one another in a variety of ways, resulting in the formation of compounds with distinct characteristics. The nature of the reaction depends on the metals and Non-Metals involved and the conditions in which the reaction occurs.

Following subtopics will be discussed in the section 3.3:

       3.3.1 Properties of ionic compounds

3.4 Occurrence of Metals: The crust of the earth is the primary source of metallic elements. Sea water also contains some soluble salts, including sodium chloride and magnesium chloride, among others. The elements or compounds that are naturally present in the earth's crust are called minerals. Some minerals contain a high percentage of a specific metal and can be mined profitably for that metal, known as ores.

Following subtopics will be discussed in the section 3.4:

       3.4.1 Extraction of Metals

       3.4.2 Enrichment of Ores

       3.4.3 Extracting metals low in the activity series

       3.4.4 Extracting Metals in the middle of the activity series

       3.4.5 Extracting Metals towards the top of the activity series

       3.4.6 Refining of Metals

3.5 Corrosion: Corrosion is a natural process that happens to metal and non-metallic materials as a result of chemical or electrochemical interactions with their environment. Over time, corrosion can cause material damage and structural damage of object.

Following subtopics will be discussed in the section 3.5:

       3.5.1 Prevention of Corrosion

Key Features of Class 10 Science Chapter 3

• Elements are classified in two types which are metal and non-metal.
• Metals are shiny, flexible, ductile, and conduct heat and electricity.
• Metals are solid elements, except for mercury which is a liquid.
• Metals can lose electrons to other metals to form positive ions.
• Metals react with oxygen to create basic oxides, such as aluminium oxide or zinc oxide. Both basic and acidic oxides are amphoteric.
• Different metals react with water or dilute acids in different ways.
• Some common metals are arranged in the order of decreasing reactivity as an activity series, such as hydrogen.
• Hydrogen can be displaced from dilute acids by a metal.
• A more reactive metal can be displaced from a less reactive salt solution by a more reactive metal.
• Process of extracting metals from ores is termed as metallurgy.
• Corrosion is a phenomenon that occurs when the surface of certain metals, including iron, is exposed to moisture for an extended period of time.
• Non-metals, on the other hand, possess properties that are opposite to those of metals, such as being neither malleable nor ductile. Furthermore, they are not good conductors of heat or electricity, with the exception of graphite, which conducts electricity.
• When non-metals react with metals, they generate negatively charged ions by capturing electrons.

Frequently Asked Questions

Question 1: What are metals and non-metals?

Answer 1: There are two broad groups of elements that make up the periodic table: metals and nonmetals. Metals are usually solid and shiny. They conduct heat and electricity well. They usually have high melting points and low boiling points. Non-metals can be solid, liquid, or gas. They usually have lower melting points and lower boiling points than metals.

Question 2: What are the main differences between metals and non-metals?

Answer 2: Metals are shiny, flexible, ductile and conduct electricity and heat well. Nonmetals do not have these characteristics and are generally conductors of both heat and electricity poorly.  Metals form positively ions which are known as cations, while nonmetals create negatively ions, which are known as anions.
