Electron Configuration with shortcut for Organic Chemistry VidIntro to Orgo Series: Video 5
This tutorial video is designed to help new and incoming organic chemistry students build a solid foundation for organic chemistry.

This video has additional examples of finding the electron configuration of larger atoms and the shortcut version using the noble gas kernel.

Video 4 (Electron Configuration Part 1) showed the introduction.

  1. I know carbon has 6 electrons, how come it looks like he has 8 electrons when you write its electron configuration? 1s2-2s2-2p4? Thanks.

  2. is it possible to write Noble gas configurations in an excited state? And how would you write normal excited state electron configurations?

  3. I’m confused with noble gas configuration of Carbon..??

    • Carbon is not a noble gas, however the kernal or internal shell can be related to the noble gas Helium

      • Ok, I understand that. But why is the electron configuration for carbon 1s2 2s2 2s4, instead of 1s2 2s2 2p2. Wouldn’t thwt make [He] 2s2 2p2 ?

  4. Why didn’t you include the d orbital in the shortcut for the electron configuration?

    • The ‘d’ orbital is a high energy orbital, however it occurs at a lower level overall. This means that while it is identified later on, it’s actually in the shell below and therefor not part of the valence. I know this can be confusing, and so keep in mind this trick: Valence refers to the outermost s and p orbitals

  5. i love ur videos …..It was really helpful !!!! thank u soooo much 🙂
