NCERT Solutions For Class 11 Chemistry Chapter 2 – Structure Of Atom: Chapter Description
The structure of an atom, theoretically consisting of a positively charged nucleus surrounded and neutralized by negatively charged electrons revolving in orbits at varying distances from the nucleus. Atoms are the building blocks of elements. They are the smallest parts of an element that chemically react. This chapter deals with atomic and molecular masses along with the mole concept, chemical reactions, and molecular formula. Students will also learn about Dalton’s atomic theory.
In this chapter, students will be solving many practical questions based on the concepts. This will help students understand the concepts better. This is a very important chapter from the exam point of view and at least one question is asked in the exam every year. Also, this is low input and high yield chapter.
Important Topics: Bohr Model, Heisenberg uncertainty principle, Debroglie equation, Photoelectric effect and Hydrogen effect.
