NCERT Exemplar Class 8 Science Chapter 4: Materials – Metals and Non-Metals
NCERT Exemplar Solutions for Class 8 Science Chapter 4 – Materials: Metals and Non-Metals helps students understand the properties, uses, and reactions of metals and non-metals. The chapter begins with the physical properties of metals such as malleability, ductility, conductivity, and lustre, which make them useful in industries and daily life. On the other hand, non-metals are explained as brittle, poor conductors, and dull in appearance, with exceptions like graphite. A major section of the NCERT Solutions for Class 8 Science covers the chemical properties of metals and non-metals. Students learn how they react with oxygen, water, acids, and bases, and how these reactions produce oxides, hydrogen gas, and salts. The displacement reaction and its applications in real life are also discussed. The chapter also explains the uses of metals in construction, transport, and electrical appliances, while non-metals like oxygen, nitrogen, and sulfur are highlighted for their importance in life processes and industries.
By solving the NCERT Exemplar Solutions for Class 8 Science Chapter 4, students get clarity on the differences between metals and non-metals, their occurrence in nature, and their significance in everyday life. This chapter strengthens both theoretical understanding and practical applications for exams.
