CBSE Class 10 Science Chapter 3 Metals and Non-Metals Worksheet with Answers

Before diving into the worksheet, revisit key concepts from NCERT Class 10 Science Chapter 3. Metals are elements that are malleable, ductile, lustrous, and good conductors of heat and electricity. They form cations by losing electrons and typically form basic or amphoteric oxides. Non-metals are brittle in solid state, poor conductors (except graphite), and form anions by gaining electrons; their oxides are acidic or neutral. The reactivity series arranges metals in order of decreasing reactivity: potassium, sodium, calcium, magnesium, aluminium, zinc, iron, lead, copper, silver, and gold. Highly reactive metals like sodium and potassium are extracted by electrolytic reduction, while moderately reactive metals like zinc and iron are extracted by reduction with carbon. Less reactive metals like mercury and copper can be extracted by heating their ores. Corrosion is the gradual degradation of metals due to reaction with oxygen, moisture, and acids in the environment; rusting of iron is the most common example.

This worksheet is designed for comprehensive practice and self-assessment of CBSE Class 10 Science Chapter 3 Metals and Non-Metals. It contains 50+ questions distributed across five sections plus one case-study question, matching the latest CBSE examination pattern introduced for 2024-25 and continuing into 2025. The difficulty level is moderate to challenging, with a mix of recall-based, application-based, and higher-order thinking questions. Suggested time for completion is 90 minutes under exam-like conditions for best results. Print the worksheet, attempt all sections sequentially without referring to your textbook or notes, then use the detailed answer key provided at the end to self-evaluate. Mark your correct and incorrect responses, calculate your percentage, and identify weak areas that need further revision. This worksheet is particularly useful for students aiming to score above ninety percent in their CBSE Class 10 Science board examination, as Chapter 3 typically contributes six to eight marks to the total paper.

This section contains eight multiple-choice questions testing your understanding of physical properties, chemical properties, reactivity series, extraction methods, and corrosion of metals and non-metals. Each question carries one mark. Select the most appropriate option from the four choices given. No negative marking, so attempt all questions even if you are unsure. These MCQs mirror the pattern seen in CBSE Class 10 Science board papers from 2023-25, where four to five MCQs from this chapter are commonly included in the question paper.

Complete the following six statements by filling in the appropriate word or phrase in the blank spaces. Each blank carries one mark. Write concise, accurate answers using terminology from your NCERT Class 10 Science textbook. Focus on spellings—incorrect spelling may lead to mark deduction in board exams. This section tests your recall of definitions, chemical names, and factual knowledge related to metals and non-metals properties and reactions.

This section has two parts. Part I contains five items in Column A that need to be matched with appropriate descriptions or examples in Column B. Write the correct pairs (e.g., 1-d, 2-a) in your answer sheet. Part II contains five true/false statements; write 'T' for true and 'F' for false. If a statement is false, rewrite it correctly to earn full marks—this is a common requirement in CBSE Class 10 Science board exams. This section tests your ability to connect concepts, differentiate between similar terms, and identify factual accuracy.

Answer the following five short-answer questions in two to three sentences or 30-50 words each. These questions carry two to three marks and require clear explanations, definitions, or descriptions. Use scientific terminology from your NCERT textbook. Where applicable, write balanced chemical equations to support your answer—equations without balancing will lose marks. This section accounts for approximately ten to fifteen marks in a typical CBSE Class 10 Science board paper and tests your ability to articulate concepts concisely.

This section contains three long-answer questions, each carrying five marks. Answer in about 80-100 words, providing detailed explanations, multiple points, chemical equations, and examples wherever necessary. These are higher-order thinking skill (HOTS) questions that test your ability to apply knowledge, analyse situations, and synthesise information from different parts of the chapter. Marks are awarded for content accuracy, clarity of explanation, correct chemical equations, and logical flow. Practising such questions is crucial for scoring above ninety-five percent in CBSE Class 10 Science board examinations.

The CBSE board introduced competency-based case-study questions in 2021, continuing through 2024-25. Read the following passage carefully and answer the four sub-questions that follow. Each sub-question carries one mark. This section tests your ability to comprehend scientific information presented in real-world contexts and apply chapter concepts to analyse, interpret, and solve related problems. Case studies often integrate multiple concepts from the chapter, so read attentively and refer back to the passage while answering.

Below is the comprehensive answer key for all questions in this CBSE Class 10 Science Chapter 3 Metals and Non-Metals worksheet. Each answer includes a brief explanation or reasoning to help you understand the correct response and learn from any mistakes. Use this key for self-assessment: mark each question as correct or incorrect, calculate your total score, and convert it to a percentage. If you score below seventy percent, revisit the NCERT textbook and your Class 10 Science notes thoroughly. If you score above eighty-five percent, you are well-prepared for this chapter in the board exam.

To extract maximum learning value from this worksheet, follow a structured approach. First, ensure you have completed reading NCERT Class 10 Science Chapter 3 Metals and Non-Metals and solved all in-text and end-of-chapter questions. Then, print this worksheet and set a timer for ninety minutes. Sit in a quiet place with no distractions, and attempt all sections sequentially as if you are taking a real test. Do not refer to your textbook, notes, or any external resources during the attempt. After completing, take a short break, then use the answer key to mark your own paper honestly. Calculate your score for each section and overall percentage. Identify patterns: are you weak in MCQs, or do you struggle with long-answer questions? Do you make errors in chemical equations or spellings? Based on this analysis, revisit specific topics in the NCERT textbook. For concepts you find difficult, watch video explanations or solve additional problems from reference books. Reattempt the worksheet after a week to check improvement. This iterative practice is the key to mastering CBSE Class 10 Science and scoring high marks in the board examination.

Metals and Non-Metals is one of the most scoring and frequently examined chapters in the CBSE Class 10 Science board paper. Typically, this chapter contributes six to eight marks directly through a mix of MCQs (one to two questions), short-answer questions (one question of two to three marks), and one long-answer or case-study question (four to five marks). Additionally, concepts from this chapter—such as reactivity series, ionic bonding, and extraction of metals—are often integrated into questions from other chapters like Chemical Reactions and Equations (Chapter 1) or Carbon and its Compounds (Chapter 4). The 2024 and 2025 CBSE Class 10 Science board papers both featured one five-mark question on corrosion and prevention, one three-mark question on reactivity series and displacement reactions, and two MCQs testing physical properties and extraction methods. The chapter is conceptually moderate; with consistent practice using worksheets like this one, students can reliably secure full marks from this chapter. Focus on writing balanced chemical equations accurately, using correct chemical names and formulae, and providing clear, structured explanations in long-answer questions.

Beyond this worksheet, CBSE Class 10 students should practise extensively from multiple sources to master Chapter 3 Metals and Non-Metals.
