How to write electron configurations and what they are

Writing electron configuration for different elements is quite simple with the use of a periodic table. Simply split the periodic table into s,p,d and f blocks and use the period # to determine the energy level (d 1 behind, f 2 behind)
If you are interested in this video, you might like my new book Teaching Introductory Chemistry www.amazon.com/dp/B0B6XQBC6T
Exceptions to this do occur for Cr, Cu and many others in the transition metals.
Ions have additional electrons or missing electrons
IE F 1s2 2s2 2p5 and F- is 1s2 2s2 2p6
Na is 1s2 2s2 2p6 3s1 and Na+ is 1s2 2s2 2p6
An electron configuration is a simple description where labels are applied to each electron in an element that later can be used to discuss why electrons exhibit specific behaviors in ionization energies, chemical reactions and bonding.
The rules for why electron configurations are what they are come from quantum mechanics and some basic information about quantum numbers and the rules such as Hund's rule, Pauli's exclusion principle and the Aufbau principle are discussed.

tried like 15 other videos and I was still super confused, Watched this once and my brain exploded with pure knowledge. 10/10 would recommend to all chemistry 1 students

Now this is what a class is when a teacher KNOWS his stuff. The most amazingly simple way of explaining smt of higher level needs exceptional skills. Respect ! 🙏 and its the first time i forgot that the vedio was so long ( educational vedio wise ). Thats magic

Great teaching. My only critique is when you do the orbital filling diagram, the arrows should be HALF arrows to denote it’s only only electron. The double arrow is reserved for electron pairs.
@julianwooten1172
@julianwooten1172 4 года назад
