Important Topics Covered in Class 10 Science Chapter 3

Metals and non-metals are the two main kinds of elements that were shown in Class 10 Science.

Most of the metals are silver, colored, and the features of such metals are that they are malleable, ductile, and good conductors of heat and electricity. All metals, apart from mercury, which is in liquid state, are generally solid at room temperature.

Metals give electrons to non metals and become positively charged ions (cations). Most metals by their reactions with oxygen form oxides that are basic.

Aluminum oxide and zinc oxide are different from the rest since they have both acid and base properties and are therefore called amphoteric oxides.

Water and dilute acids react with different metals to varying degrees, depending on their reactivity. The activity series provides a list of metals organized in a sequence of decreasing reactivity. Metals that are placed above hydrogen in the series of activity can replace hydrogen from dilute acids.

Non-metals accept electrons from metals and thus a negatively charged anion is formed. Non-metals usually give rise to acidic or neutral oxides and do not displace hydrogen from acids but react with hydrogen to give hydrides.

NCERT Exercise Questions with Solutions

The NCERT Exercise Questions for Class 10 Science Chapter 3, Metals and Non-Metals, Metals help the students to gain an accurate knowledge of the features of metals and non, metals. Solutions to the questions have been derived from the current NCERT syllabus and thus are very important for the board exam preparations.

Following top, notch, concise and easy, to understand answers have been prepared for the main NCERT exercise questions.

Q.1 Cite a metal which is:
(a) in liquid state at the normal room temperatures
(b) can be easily cut with a knife
(c) has the highest electrical conductivity

Answer:
(a) Mercury
(b) Sodium
(c) Silver

Q.2 What led you to consider copper as the best metal for electric wires?

Answer:
Copper is the only one metal for electric wires because it is so good conducting and ductile that even if the wire is made very thin it would still be unbroken.

Q.3 What occurs during the reaction between metals and oxygen?

Answer:
Metals react with the oxygen then they form metal oxides with basic nature except in some cases a weak metal is the reason for an oxide of acidic nature being formed.
Example: Magnesium + Oxygen → Magnesium Oxide

Q.4 What factors lead to the classification of aluminium and zinc as amphoteric metals?

Answer:

Zinc and aluminum are included in the amphoteric metal list that also contains their sulfides, hydroxides and oxides, as the metal compounds formed can neutralize both acids and bases and thus salts and water are made as a result.

Q.5 What is the reactivity series and what does it contain?

Answer:
The reactivity series is a soft of hierarchy of metals according to their reactivity starting from the most reactive to the least reactive one. Furthermore, this series indicates not only the possibility of displacement reactions but also the extraction methods of metals from ores.

Q.6 What is the reason behind the displacement of hydrogen by metals from dilute acids?

Answer:
The interaction of metals with acids is so powerful that alongside the displacement of hydrogen, the metals also cause the formation of salts with the concurrent release of hydrogen gas.

Q.7 What will be the result of non-metals’ reaction with oxygen?

Answer:
The non-metals reacting with oxygen will produce oxides that are either acidic or neutral and they will be the nature of the oxides.
Example: C + O2 → CO2 (acidic oxide)

Q.8 What is meant by corrosion? And can you give one example?

Answer:

Corrosion is the term used to describe the gradual and slow destruction of metals primarily due to their interaction with air, moisture or chemicals.
For example: Iron rusting.

Q.9 Indicate two methods to prevent corrosion.

Answer:

The techniques are:

• Coating
• Galvanizing

Q.10 What are the causes of the hardness and brittleness of ionic substances?

Answer:
Hardness and brittleness of ionic materials are associated with their

FAQs

1. How can the NCERT Solutions assist students in figuring out the exercise questions of Chapter 3 Science Class 10 in a simpler manner?

The NCERT Solutions present precise and thorough responses to all the exercise questions of Chapter 3, and they are in strict compliance with the latest marking scheme. They provide students with directions on the manner to tackle, solve and also give chemical equations and conceptual questions, thus making it easier and better for them to understand and improve their answer-writing skills during the examinations.

2. What is the reactivity series meaning, and how is it used in the master answers of this chapter?

The reactivity series is essentially a list of metals organized according to their chemical reactivity, with the most reactive metal placed first. The importance of it could be briefly stated as:

• Foreseeing the metals that are able to displace others in single displacement reactions
• Describing the facts like which metals form oxides more easily, or react with acids and water very mildly
• The right choice of extraction methods from ores
• Understanding this series becomes the key to solving many exercise questions in Chapter 3.

3. Why are metals like sodium and potassium stored under oil?

The metals sodium and potassium are very reactive that is why they are stored under oil so that the possibility of their reaction with the oxygen and moisture in the surrounding air is avoided. Reactions of this kind may result in fire or explosions; thus, this is a very common conceptual question which appears in NCERT Solutions for Class 10 Science Chapter 3.

4. How does the NCERT Solution explain the prevention of corrosion and rusting of metals?

The solutions mention various methods of rust prevention, such as:

• Painting or greasing: Such a technique acts as a barrier to air and moisture at the same time.
• Galvanisation: The method through which zinc is applied to iron for protection.
• Alloying: The practice of joining metals to increase their resistance to rust.

The explanation of each method is accompanied by examples that are in accordance with the exam patterns and are done stepwise.

5. How can using the NCERT Solutions for Science Chapter 3 help improve exam performance?

• Clarifies concepts and sharpens one’s ability to solve problems
• Structures answers in a manner expected in exams
• Increases one’s confidence to face both direct and higher-order application questions

These advantages are directly reflected in the performance of students in board and school tests.
