Concise Selina Solutions for Class 9 Chemistry Chapter 6 Study of the First Element Hydrogen


In chemistry, we will study the first Element Hydrogen. Hydrogen is the first element in the periodic table as its atomic number is 1. Hydrogen has properties similar to that of Alkali metals and Halogens. Henry Cavendish discovered Hydrogen. Hydrogen is the lightest element and the most abundant element in the universe. Its atom consists of just a proton and an orbiting electron. Without Hydrogen we would not be here; all organic compounds making up living things contain Hydrogen and it is also a constituent of water, necessary for all known life. Hydrogen is arguably an essential element of life.

ICSE chemistry solutions provide deeper insights into the position of Hydrogen in the periodic table. After studying this study material, students will acquire knowledge of Hydrogen from water, displacement of Hydrogen from alkalis, preparation and collection of Hydrogen, Industrial manufacture of Hydrogen by Bosch process, oxidation, reduction reaction, and their importance.
