Understanding Electrons and Orbitals

The video tutorial explains how to find the electron configuration for Boron using the periodic table. It starts by identifying the number of electrons in Boron, which is equal to the number of protons. The tutorial then guides viewers through the process of filling the 1s, 2s, and 2p orbitals to achieve the correct electron configuration. The final configuration is confirmed by ensuring the total number of electrons matches the atomic number of Boron.
