1. NCERT Solutions Class 11 Chemistry Chapter 2 Structure of The Atom NCERT Solutions for Class 11 Chemistry Chapter 2 Structure of The Atom is the most effective way to learn about it. Consult our NCERT Solutions to learn the fundamentals of this chapter and to prepare for CBSE term 1 board exams as well as competitive exams such as JEE Mains, JEE Advance, Olympiad, NTSE, and others. Subject matter experts created these NCERT Solutions to provide an in-depth analysis of all of the concepts covered here. This study guide is based on the most recent CBSE curriculum. We discussed all types of NCERT exercise questions as well as intext questions in this NCERT Solutions Class 11. In NCERT Solutions Class 11 we have to study various important topics such as: •Atom Structure - An atom is the smallest constituent particle of matter. A positive nucleus is surrounded by a cloud of negatively charged particles to form an atom. Positively charged particles make up the positive part of the atom. The proton and neutron are positively charged atom particles, while the electron is negatively charged.

2. •Subatomic Particles Discovered - It was previously thought that an atom could not be further divided into smaller particles. However, in an experiment conducted by scientists in the nineteenth and early twentieth centuries, it was discovered that atoms are made up of smaller particles known as subatomic particles. An atom's three subatomic particles are: oNeutron – which has no charge oElectrons – which are negatively charged oProton – which is positively charged •Atomic Models– after the discovery of the atom many scientists have proposed lots of atomic models throughout the history of modern physics. There are a total of 5 atomic models. oJohn Dalton's atomic model: Dalton´s Billiard Ball (Solid Sphere) Model. oJ.J. Thomson's model: Plum Pudding model. oErnest Rutherford's model: nuclear model. oNiels Bohr's model: Planetary model. oErwin Schrödinger's model: Electron Cloud Model/Quantum Model. •Developments Leading to Bohr’s Model of Atom – oNiel Bohr describes the atom with the help of the concept of quantization. oElectrons revolve in an orbit and never lose their energy. oIn an atom, the electron moves from a higher orbit to a lower orbit when it losses energy and if the electron moves from a lower orbit to a higher orbit it gains energy. •Bohr’s Model for Hydrogen Atom - Bohr’s prediction for smaller hydrogen atoms was correct, but it had its setback in describing the structure of larger atoms. •Quantum Mechanical Model of the Atom– the quantum mechanical model of an atom consists of ideas such as shells, sub-shells, and orbitals. It is also based on Schrodinger’s wave equation.
