The Periodic Table: Atomic Number

The video tutorial explains the concept of atomic numbers by comparing them to unique identifiers like license plate numbers. It highlights that no two elements have the same atomic number, similar to how no two cars share a license plate. The tutorial further delves into the atomic structure of carbon, which has six protons, and nitrogen, which constitutes about 70% of our air and has an atomic number of seven. The importance of atomic numbers in categorizing elements is also discussed.
