NCERT Solutions for Class 11 Chemistry Chapter 2 Structure of Atom

In this chapter, we study about the discovery of fundamental particles like electron, proton and neutrons. Chapter 2 Structure of atom deals with the various advancements being made to explain different atomic models which gave the basic concept of quantization of energy and gave a modern structure of atoms. In this chapter, there is 67 question in the exercise. The NCERT Solutions for Class 11 Chemistry Chapter 2 Structure of Atom are prepared by our subject experts. These NCERT solutions help students to clear their doubts.     

The rich diversity of chemical behaviour of various elements can be discovered to the differences in the internal structure of atoms of these elements. The NCERT Class 11 Chemistry Chapter 2 Structure of Atom start with some experimental observations made by scientists towards the end of 19th and beginning of the 20th century. According to these observations, atoms are made of sub-atomic particles, such that protons, electrons and neutrons. This concept is very different from Dalton's atomic theory.

After completing Class 11 Chemistry Chapter 2 Structure of Atom, students will be able to know about the discovery of proton, electron and neutron; describe Rutherford, Thomson and Bohr atomic models; understand nature of Planck's quantum theory and electromagnetic radiation; explain the photoelectric effect; state the de Broglie relation and Heisenberg uncertainty principle. This chapter also explains atomic orbitals in terms of quantum numbers, Pauli exclusion principle, Aufbau principle and Hund's rule of maximum multiplicity. and at the end of chapter students will learn how to write the electronic configurations of atoms.
