Chapter 2 – Hydrogen<\/strong><\/h2>\n\n\n\n

Chapter 9 \u2013 Hydrogen discusses the position of hydrogen in the periodic table and its unique properties. Although placed in Group 1, hydrogen shows similarities with both alkali metals and halogens. The chapter explains its isotopes \u2013 protium, deuterium, and tritium<\/strong>, and their characteristics.<\/p>\n\n\n\n

Students learn about the preparation, properties, and uses of hydrogen<\/strong>, including its role as a clean fuel. The chapter also covers hydrides (ionic, covalent, and metallic)<\/strong> and the concept of hydrogen bonding<\/strong>, which explains special properties of water and other compounds. This topic is important for understanding chemical bonding and is relevant for CBSE board exams, NEET<\/a>, and JEE preparation.<\/p>\n\n\n\n
