Assertion and Reasoning Questions on Periodic Properties and Variation of Properties for ICSE Class 10 Chemistry
Assertion and reasoning questions are also known as assertion reason questions. Assertion-Reason questions are a type of question format used in ICSE exams where two statements are provided: an Assertion (A) and a Reason (R). Students need to determine whether each statement is true or false and if the Reason correctly explains the Assertion.
Directions:
(a) Assertion and Reason both are correct statements and reason is the correct explanation of the assertion.
(b) Assertion and Reason both are correct statements, but reason is not the correct explanation of the assertion.
(c) Assertion is true, but reason is false.
(d) Assertion is false, but reason is true.
Q. 1. Assertion: The elements of the different group have similar chemical properties.
Reason: It is because they have same number of valence electrons.
Difficulty Level: Medium
Ans. (a) Assertion and Reason both are correct statements and reason is the correct explanation of the assertion.
Explanation:
The elements of the same group have similar chemical properties because of the presence of same number of valence electrons. Thus, assertion is false but reason is true.
Q. 2. Assertion: Metalloids are present in zig-zag rows in periodic table.
Reason: Metalloids have same properties.
Difficulty Level: Medium
Ans. (b) Assertion and Reason both are correct statements, but reason is not the correct explanation of the assertion.
Explanation:
Metalloids are present in zig-zag rows because they have some properties of metals and some properties of non-metals. Thus, both assertion and reason are true but reason is not the correct explanation of the assertion.
Q. 3. Assertion: Chlorine is called halogen.
Reason: It is because chlorine reacts with metals to form salts.
Difficulty Level: Medium
Ans. (a) Assertion and Reason both are correct statements and reason is the correct explanation of the assertion.
Explanation:
Elements such as chlorine, bromine and iodine are called halogens because they react with metals to form salts. Thus, assertion and reason both are correct.
We hope the given ICSE assertion reasoning questions for Periodic Properties and Variation of Properties helps you in your learning.

Frequently Asked Questions (FAQs) on Periodic Properties and Variation of Properties ICSE Class 10 Chemistry Assertion and Reasoning Questions
Q1: What are Assertion and Reasoning questions?
A1: Assertion and Reasoning questions are a type of question format used in ICSE exams where two statements are provided: an Assertion (A) and a Reason (R). Students need to determine whether each statement is true or false and if the Reason correctly explains the Assertion.
Q2: How do Assertion Reasoning questions differ from other question types?
A2: Unlike multiple-choice questions, Assertion-Reason questions require students to analyze the relationship between two statements. It’s not just about knowing the facts but understanding how they connect logically.
Q3: What steps should I follow to correctly answer Assertion and Reasoning questions?
A3: Follow these steps:
Read both statements carefully. Understand what each statement is saying.
Determine the truth value of each statement. Decide if each statement is true or false independently.
Analyze the relationship. If both statements are true, decide whether the Reason (R) correctly explains the Assertion (A).
Choose the correct option. Based on your analysis, select the appropriate answer from the given options.
Q4: What options are typically provided for Assertion and Reasoning questions?
A4: The typical options are:
A. Both A and R are true, and R is the correct explanation of A.
B. Both A and R are true, but R is not the correct explanation of A.
C. A is true, but R is false.
D. A is false, but R is true.
Q5: What should I check to determine if the Reason correctly explains the Assertion?
A5: Ensure that the Reason provides a logical explanation for the Assertion. Check if the Reason directly addresses the cause or basis of the Assertion and if they are contextually linked.
Q6: How can I improve my skills in answering Assertion and Reasoning type questions?
A6: Practice regularly with sample questions and past papers. Focus on understanding the concepts thoroughly rather than rote memorization. Analyzing how different facts and concepts interrelate will enhance your ability to correctly answer these questions.
Q7: What are common mistakes to avoid when answering Assertion and Reasoning questions?
A7: Common mistakes include:
Not reading the statements carefully and missing key details.
Assuming the Reason explains the Assertion without checking the logical connection.
Confusing the order or relationship between the statements.
Overthinking and adding information not provided in the question.
Q8: What resources can help me practice Assertion and Reasoning questions for ICSE Class 10 Chemistry?
A8: Use study guides specifically designed for Assertion-Reason questions. Online educational platforms and reference books for ICSE Class 10 Chemistry also offer practice questions and explanations. xamcontent.com/cisce also provides assertion reason questions for ICSE Class 10 Chemistry.
