Electron Configuration and Atomic Structure

The video tutorial explains how to find the electron configuration for carbon by using the periodic table. It starts by identifying the number of electrons in a carbon atom, which is equal to its atomic number. The tutorial then guides viewers through writing the electron configuration notation, using the 1s, 2s, and 2p orbitals, and concludes by verifying the configuration as 1s2 2s2 2p2.
