Nature of matter

In Class 11 Chemistry, this topic introduces the fundamental nature of matter as part of “Some Basic Concepts of Chemistry.” Students learn that matter has mass, occupies space, and is made of tiny particles. They explore the states of matter, physical and chemical properties, and the classification of substances into elements, compounds, and mixtures. The topic also builds a foundation for understanding atoms, molecules, composition, and the quantitative ideas developed in later chemistry chapters.
