Chemistry: What Makes Us Stick Together?

by Texas Instruments - Simulation Lesson


  • Students will determine the ratio of two nonmetals needed to form a stable covalent compound or polyatomic ion.
  • Students will relate the sharing of electrons to the formation of molecules.
  • Student will learn how to write formulas for covalent compounds.

About the Lesson

This simulation gives a macroscopic view of what occurs microscopically when two nonmetals react.
As a result, students will:

  • Better understand how molecules are formed.
  • Be able to write formulas for covalent compounds.
