Video Tutorial – Structure of Atom, Class 11 and 12 | Part 4 | By Prof. Sabyashachi Mishra of IIT – Kharagpur

In the fourth part of the series “Structure of Atom” Prof. Sabyashachi Mishra of IIT – Kharagpur goes into a deeper explanation of the atomic structure, with Neil Bhor’s Atomic Model and how it addresses the drawback of Rutherford’s atomic model. Postulated of Neil Bhor in details, concept of orbit and orbitals and energy emission in them. He also explains the particle and wave like nature of the matter and limitation of Neil Bhor’s atomic model.

This video tutorial covers the following areas of inorganic chemistry as per syllabus of class XI and XII NCERT and other major boards of India

Neil Bohr’s Model of Atom 

Drawbacks of Rutherford’s atomic model  

Stability of an atom 

Postulates of Neil Bohr in details  

Results obtained from Bohr’s Atomic Model 

Orbits are numbered 

Radius of Orbit 

Speed of Electron in orbit n 

Energy in orbit n 

Concept of Free Electron – Ions 

Interpreting Emissions spectrum of Hydrogen Atom by Bohr’s atomic model 

Energy level analysed by emission spectrum and interpreting them by Bohr’s atomic model 

Explaining Lyman Series, Balmer Series, Paschen Series,  

Why we get a series of lines separated from each other in an emission spectrum of Hydrogen  

When and why do we get bands in Emission Spectrum of Hydrogen 

 

Limitations of Bohr’s Atomic Model 

Can only explain single electronic species. 

Cannot explain the splitting of spectral lines in magnetic field or electric field thus Could not explain Zeeman Effect or Stark Effect 

Cannot explain chemical bonding 

 

de Broglie’s Hypothesis – Can Matter have a Wave Like Nature ? 

Particle has a wave nature – an explanation
