Chemistry: Atomic Structure and Chemical Bonding

By Prof. K. Mangala Sunder | IIT Madras

Learners enrolled: 1332

The course is a rigorous introduction to principles of quantum chemistry and also describes all mathematical details at the introductory level, accurately however. It is limited to elementary model problems, angular momentum and spin and an introduction to chemical bonding in one and two-electron systems.

PRE-REQUISITES: Mathematics –integral and differential calculus (minimally, one variable), elementary first order differential equations and Matrix algebra—Eigenvalue –eigen vector analysis;

Introduction to modern physics –Planck’s radiation law, Einstein’s theory on photoelectric effect and wave particle duality.

INDUSTRY SUPPORT: This is a core course. I do not expect any industry to be a specific sponsor

Course certificate

The course is free to enroll and learn from. But if you want a certificate, you have to register and write the proctored exam conducted by us in person at any of the designated exam centres.
The exam is optional for a fee of Rs 1000/- (Rupees one thousand only).
Date and Time of Exams: 23 April 2022 Morning session 9am to 12 noon; Afternoon Session 2pm to 5pm.
Registration url: Announcements will be made when the registration form is open for registrations.
The online registration form has to be filled and the certification exam fee needs to be paid. More details will be made available when the exam registration form is published. If there are any changes, it will be mentioned then.
Please check the form for more details on the cities where the exams will be held, the conditions you agree to when you fill the form etc.

CRITERIA TO GET A CERTIFICATE

Average assignment score = 25% of average of best 8 assignments out of the total 12 assignments given in the course.
Exam score = 75% of the proctored certification exam score out of 100

Final score = Average assignment score + Exam score

YOU WILL BE ELIGIBLE FOR A CERTIFICATE ONLY IF AVERAGE ASSIGNMENT SCORE >=10/25 AND EXAM SCORE >= 30/75. If one of the 2 criteria is not met, you will not get the certificate even if the Final score >= 40/100.

Certificate will have your name, photograph and the score in the final exam with the breakup.It will have the logos of NPTEL and IIT Madras. It will be e-verifiable at nptel.ac.in/noc.

Only the e-certificate will be made available. Hard copies will not be dispatched.

Once again, thanks for your interest in our online courses and certification. Happy learning.
