Exploring Atomic Theory and the Periodic Table

This video tutorial covers the basics of atomic structure and theory, starting with the contributions of early scientists like Dalton, Thompson, Millikan, and Rutherford. It explains the structure of atoms, including protons, neutrons, and electrons, and discusses isotopes and atomic mass calculations. The tutorial also provides an overview of the periodic table, highlighting the organization of elements into groups and periods. The video concludes with additional resources for further study.
