Periodic Table and Periodicity MCQs With Explanations

Q1. Which one is the shortest period in the periodic table:
The first period contains only two elements (H and He), making it the shortest period in the periodic table.
Q2. Number of elements placed in 6th period is:
The 6th period includes the lanthanides, totaling 32 elements due to filling of 4f, 5d, and 6s orbitals.
Q3. Transition elements are:
Transition elements are all metals, characterized by incomplete d-subshells and typical metallic properties like conductivity and malleability.
Q4. Horizontal rows of the periodic table were called:
Horizontal rows in the periodic table are termed periods, reflecting the periodic repetition of properties as atomic number increases.
Q5. The element having less value of ionization energy and less value of electron affinity is likely to belong to:
Group 1 elements have the lowest ionization energy and very low electron affinity due to their large size and single valence electron.
Q6. Which element has the highest melting point?
Among alkali metals, sodium has the highest melting point due to stronger metallic bonding compared to heavier members like K, Rb, and Cs.
Q7. Which element is the most reactive element?
Fluorine is the most reactive element due to its highest electronegativity and smallest atomic size, enabling strong electron attraction.
Q8. How many electrons can nitrogen accept in its outermost shell?
Nitrogen has 5 valence electrons and needs 3 more to complete its octet, so it can accept up to 3 electrons.
Q9. A yellow solid element exists in allotropic forms which is also present in fossil fuel indicate the name.
Sulphur is a yellow solid with allotropes like rhombic and monoclinic sulfur and is found in fossil fuels as organic sulphur compounds.
Q10. Which is the softest metal?
Sodium is the softest among the listed metals and can be cut with a knife due to its low metallic bonding strength.
Q11. Identify the electronic configuration of the outermost shell of a transition metal.
Transition metals have their outermost electrons in the ns² orbital and partially filled (n-1)d orbitals, giving the general configuration ndˣ ns².
Q12. In which period and group will you place the element which is an important part of the solar cell?
Silicon, a key element in solar cells, is in the 3rd period and 14th group of the periodic table.

After Chapter 8: Periodic Table and Periodicity, Practice Next Chapters

Once you finish these MCQs, continue with the next available chapters from Chemistry so your revision stays chapter-wise and complete.

Chapter 8: Periodic Table and Periodicity Revision Guide

Complete the MCQs first, then review every incorrect answer against the textbook heading where that concept appears. For biology and other science subjects, pay attention to terminology, diagrams, sequence of processes, examples and differences between similar structures or functions.

This chapter page keeps the exact class, subject, chapter, question count, answer checking, explanations and follow-up chapters together, so students can revise from one focused URL instead of searching through the full book again.

Class 9 Chemistry MCQ Preparation: Periodic Table and Periodicity

This page supports Matric Part 1 practice in Chemistry. At this stage, the main purpose is building the definitions, symbols, rules and study habits needed for later matric work. The questions available here should be used with the current textbook and the instructions issued by the learner's school or examination board.

What Chemistry MCQs can test

In Chemistry, objective questions commonly draw on chemical symbols, atomic structure, periodic trends, bonding, equations, reaction conditions, laboratory observations and calculations. A useful answer is based on the exact wording and concept, not simply on recognising a familiar option. For this subject, learners should connect each chemical fact with a particle-level explanation and check symbols, charges, valencies and equation balance carefully.

Periodic Table and Periodicity: what to focus on

Particles, structures, symbols, trends, equations, reaction conditions and the reasons substances behave differently.

Write the relevant symbol, structure or balanced equation and compare each option with the rule demonstrated by it.

Common mistakes for Class 9 learners

In this subject, frequent errors include confusing related trends, using an incorrect chemical symbol, missing a reaction condition or treating similar compounds as identical. Separate new terms that look similar and connect every formula, rule or definition with at least one textbook example. When the page marks an answer as incorrect, the next step should be to identify the mistaken idea and verify it, rather than memorising the displayed answer letter.

A practical revision routine

Read a small textbook section, answer a focused set of MCQs and correct the underlying idea before starting the next section. Before attempting the MCQs, review definitions, equations, periodic relationships, structures, reaction conditions, examples and exceptions stated in the textbook. Complete a manageable set without notes, check the result, and divide errors into missing knowledge, misunderstood concepts and careless reading. Revise the appropriate section before repeating the chapter.

How to review Periodic Table and Periodicity after the quiz

List the questions you missed from Periodic Table and Periodicity and write the textbook heading connected with each one. Explain the correct idea in your own words, then return later and answer a fresh set. This gives the chapter page a clear purpose: finding specific weaknesses in Chemistry rather than only collecting a score.

Accuracy and responsible use

Explanations are provided where they exist in the question bank, but educational databases can contain incomplete or mistaken material. Confirm disputed answers with an authoritative textbook or teacher. Ahmad Learning Hub provides a practice resource and does not claim that a question will appear in an examination or that every available item represents an official board question.
