Lesson Plan: Chemical Names and Formulas Science

This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to name simple compounds and write their chemical formulas.


Students will be able to

  • recall the difference between an element and a compound,
  • explain how a chemical compound is formed,
  • describe the general rules used to name chemical compounds,
  • name simple chemical compounds,
  • recall the names of simple chemical compounds that do not have names related to the elements of which they consist, such as water, ammonia, and methane,
  • describe the components of a chemical formula,
  • write the chemical formulas for simple chemical compounds,
  • analyze chemical formulas to deduce elemental compositions and the ratios of atoms.


Students should already be familiar with

  • concepts of atoms and elements,
  • symbols used to represent elements.


Students will not cover

  • naming chemical formulas of binary compounds composed of elements with an atomic number greater than 20,
  • naming or writing chemical formulas of polyatomic ions other than sulfate, carbonate, hydroxide, phosphate, and nitrate.
