With the help of our solution, Students will learn about the Position of hydrogen in the periodic table:<\/p>\n<p>The position of hydrogen in the periodic table is not justified because it resembles both alkali metals as well as halogens. (i) Electronic Configuration: Hydrogen has one electron in its valence shell-like alkali metals.<\/p>\n<p>It is the most abundant element in the universe. It is rarely found in the free state in the earth\u2019s atmosphere. However, in the combined state, it is the third most abundant element on the earth\u2019s surface.<\/p>\n<p>Hydrogen has three isotopes: protium (11H), deuterium (D or21H), and tritium (T or31H). Amongst these three, the only tritium is radioactive. Despite its resemblance both with alkali metals and halogens, it occupies a separate position in the periodic table because of its unique properties.<\/p>\n<p>They also get to learn about the following with our NCERT solutions-<\/p>\n<ol>\n<li>Hydrogen-occurrence, Isotopes, Preparation, Properties, and uses<\/li>\n<li>Hydrides-ionic covalent and interstitial<\/li>\n<li>Physical and Chemical Properties of water<\/li>\n<li>Hydrogen peroxide<\/li>\n<li>Hydrogen as a fuel<\/li>\n<\/ol>\n<p>\u00a0Subtopics of Class 11 Chemistry Chapter 9 \u2013 Hydrogen<\/p>\n<ol>\n<li><em>Position Of Hydrogen In The Periodic Table<\/em><\/li>\n<li><em>Dihydrogen, H2<\/em><\/li>\n<li><em>Occurrence<\/em><\/li>\n<li><em>Isotopes Of Hydrogen<\/em><\/li>\n<li><em>Preparation Of Dihydrogen, H2<\/em><\/li>\n<li><em>Laboratory Preparation Of Dihydrogen<\/em><\/li>\n<li><em>Commercial Production Of Dihydrogen<\/em><\/li>\n<li><em>Properties Of Dihydrogen<\/em><\/li>\n<li><em>Physical Properties<\/em><\/li>\n<li><em>Chemical Properties<\/em><\/li>\n<li><em>Uses Of Dihydrogen<\/em><\/li>\n<li><em>Hydrides<\/em><\/li>\n<li><em>Ionic Or Saline Hydrides<\/em><\/li>\n<li><em>Covalent Or Molecular Hydride<\/em><\/li>\n<li><em>Metallic Or Non-stoichiometric (Or Interstitial ) Hydrides<\/em><\/li>\n<li><em>Water Ex<\/em><\/li>\n<li><em>Physical Properties Of Water Ex<\/em><\/li>\n<li><em>Structure Of Water<\/em><\/li>\n<li><em>Structure Of Ice<\/em><\/li>\n<li><em>Chemical Properties Of Water<\/em><\/li>\n<li><em>Hard And Soft Water<\/em><\/li>\n<li><em>Temporary Hardness<\/em><\/li>\n<li><em>Permanent Hardness<\/em><\/li>\n<li><em>Hydrogen Peroxide (H202)<\/em><\/li>\n<li><em>Preparation<\/em><\/li>\n<li><em>Physical Properties<\/em><\/li>\n<li><em>Structure<\/em><\/li>\n<li><em>Chemical Properties<\/em><\/li>\n<li><em>Storage<\/em><\/li>\n<li><em>Uses<\/em><\/li>\n<li><em>Heavy Water, D20<\/em><\/li>\n<li><em>Dihydrogen as a Fuel<\/em><\/li>\n<\/ol>\n<h2><span class=\"ez-toc-section\" id=\"benefits-of-the-ncert-solutions-for-class-11-chemistry-chapter-9-hydrogen\"><\/span>Benefits of the NCERT Solutions For Class 11 Chemistry Chapter 9 Hydrogen<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>With the help of our NCERT Solutions Chemistry Class 11 chapter 9 Hydrogen, students will get accustomed to the properties, reactions use of hydrogen, and other relative factors of hydrogen.<\/p>\n<p>Besides, hydrogen is an important element as it is the most common item that makes up more than 80 percent of the mass of the entire universe.
