In this video we will learn about Quantum Numbers of electrons. We will first learn all the four Quantum Numbers, i.e. Principal, Azimuthal, Magnetic and Spin Quantum Numbers, and later we will learn how to locate electrons in its respective orbital using these four Quantum Numbers. This concept will help us understand advanced topics of chemistry. Therefore, it is necessary to understand them at conceptual level.
Some of the question that are answered in this video are as followed:
0:00 Concept of Atomic Shells in Bohr's Atomic Model
0:44 Principal Quantum Number
1:35 Total number of electrons in a shell
1:42 Total number of orbitals in a shell
1:46 Azimuthal Quantum Number
2:34 Shapes of subshell and Azimuthal Quantum Number
3:36 Magnetic Quantum Number
4:50 Spin Quantum Number
5:07 Relating motion of electron with earth
4:43 Nodes in Atomic Orbitals
5:48 Why spin of electron can't describe its direction
6:07 Magnetic Moment of Electron
6:23 Difference of Energy in Atomic Orbitals
7:17 Conclusion
Topic in Courses:
NCERT Chemistry XI: Chapter 2 Structure of Atom
PTB Chemistry 11: Chapter 5 Atomic Structure
This video is seventeenth one in this series of "Basics of Chemistry". I will try to make more videos in this series. First I will cover the basics of the chemistry, then I will cover intermediate and topics and later I will discuss some advanced topics as well.
I hope you will like this video. If there is any feedback related to the video, you can give that in comments.
