Drawing Bohr Models of Atoms and Ions - 3 easy steps!

This video tutorial explains how to draw accurate Bohr models for atoms and ions. It emphasizes the importance of understanding protons, neutrons, and electrons, as well as electron configurations. The tutorial outlines three main steps: placing protons and neutrons in the nucleus, writing the electron configuration, and distributing electrons across energy levels. Examples include magnesium, sodium ion, and chlorine ion, demonstrating how to apply these steps to different elements and ions.

What is the primary purpose of the Bohr model in atomic theory?

• To predict chemical reactions
