Chapter 11Contains Standard content
Groups 15 and 16: Nitrogen and Oxygen Families, Groups 17 and 18: Halogens and Noble Gases
Air is mostly nitrogen, a match head holds phosphorus, a car battery is filled with sulphuric acid, swimming pool water is cleaned with chlorine, and a glowing sign is filled with a noble gas. All of them come from the right-hand side of the periodic table. In this chapter you learn how nitrogen, phosphorus, oxygen, sulphur, the halogens and the noble gases are made, how they react, and why their molecules have the shapes they have. It serves the Indian syllabus (NCERT, JEE Main, NEET) and the matching topics of A-Level, IB and AP Chemistry. Python balances the equations, runs the plant calculations and works out the shapes.
