Chemical Combination: The Elements and the Components of the Atom

The video tutorial introduces the basic concepts of chemistry, including elements, molecules, and atoms. It explains the structure of an atom, focusing on protons, neutrons, and electrons, and introduces key terms like mass number and atomic number. The tutorial also covers electronic configuration, using sodium as an example to illustrate how electrons are distributed across energy levels. Finally, it sets the stage for the next lesson on the classification of elements, ions, and types of bonds.

Describe the electronic configuration of sodium.
