CBSE Class 11 Chemistry Objective Questions on Periodic Table and Trends
Introduction Paragraph
The CBSE Class 11 Chemistry MCQs on “Periodic Table and Properties” are designed to help students strengthen their understanding of periodic trends and classifications based on the NCERT Class 11 Chemistry Chapter 3 syllabus. This topic introduces students to the modern periodic law, the arrangement of elements in the periodic table, and the recurring trends in their physical and chemical properties.
Our online practice test consists of carefully selected multiple-choice questions that focus on periodic trends such as atomic radius, ionization energy, electronegativity, electron affinity, and metallic character. Each question is followed by instant feedback and detailed explanations to enhance conceptual clarity.
This MCQ quiz is perfect for CBSE Class 11 board exam preparation and also serves as a strong foundation for competitive exams like JEE Main and NEET. Designed strictly as per the NCERT syllabus, these questions ensure accuracy, depth, and exam-oriented learning in an engaging and timed format.
Sample MCQs (with Answers and Explanations)
Q1. Who proposed the Modern Periodic Law?
A) Mendeleev B) Henry Moseley C) Dalton D) Rutherford
Answer: B) Henry Moseley
Explanation: Henry Moseley arranged elements by increasing atomic number, forming the basis of the modern periodic table.
Q2. Across a period from left to right, atomic radius generally:
A) Increases B) Decreases C) Remains same D) Varies irregularly
Answer: B) Decreases
Explanation: Increasing nuclear charge pulls electrons closer to the nucleus, reducing atomic radius across a period.
Q3. Which group in the periodic table contains the most reactive nonmetals?
A) Group 1 B) Group 2 C) Group 17 D) Group 18
Answer: C) Group 17
Explanation: Group 17 elements (halogens) are highly reactive due to their high electronegativity and electron affinity.
Q4. Down a group, ionization energy generally:
A) Increases B) Decreases C) Stays constant D) Fluctuates
Answer: B) Decreases
Explanation: Increased atomic size and shielding reduce the nucleus’ hold on outer electrons, lowering ionization energy.
Q5. Which of the following is isoelectronic with Ne?
A) Na⁺ B) O²⁻ C) F⁻ D) All of these
Answer: D) All of these
Explanation: Na⁺, O²⁻, and F⁻ each have 10 electrons, the same as neon, making them isoelectronic species.
