Texas Chemistry Standards (TEKS)
This lesson teaches students introductory concepts that will be needed in lessons that focus on the following TEKS:
C.7.A: The student is expected to name ionic compounds containing main group metals and covalent compounds…using International Union of Pure and Applied Chemistry (IUPAC) nomenclature rules. C.7.B: The student is expected to write the chemical formulas of ionic compounds containing main group metals and covalent compounds.
Lesson Summary:
This guided inquiry lesson enables students to construct their own understanding of basic formula and nomenclature concepts. These include: identifying metals and nonmetals, identying and using subscripts in formulas, and identifying ionic and covalent compound formulas. Students are able to actively learn the material without lectures or notetaking.

Part 1: Metals, Nonmetals, and Metalloids
• Students discover the locations of metals, nonmetals, and metalloids in the periodic table by studying an illustration of the periodic table.

• Students practice identifying elements as metals, nonmetals, and metalloids.

Part 2: Subscripts and Bonds
• Students compare illustrations of compounds to their formulas. They discover that the subscripts of a formula indicate the number of atoms in the compound and that the subscript “1” is never written in the formula.

• Students compare illustrations of compounds containing polyatomic ions to their formulas. They discover when parentheses are added around polyatomic ion groups. They also learn that the subscript outside of the parentheses indicates the number of polyatomic ion groups present in the formula.

Part 3: Ionic vs Covalent Compounds
• Students compare the types of elements in ionic and covalent compounds. They discover that ionic compounds begin with a metal element and covalent compounds begin with a covalent element.

”Formula War” Card Game
• Students practice working with subscripts and identifying ionic vs covalent compounds by playing a variation of the card game “War”.

Student Study Sheet
Students are provided with student study sheets summarizing all of the important concepts and vocabulary in this lesson.

Learning Objectives (Bloom’s Revised Taxonomy):
Remembering: Define the following terms: chemical bond, subscript, polyatomic ion.
Understanding: Use the periodic table to identify elements as metals, nonmetals, and metalloids.
Applying: Use subscripts to determine the number of each atom and atom group present in a compound.
Analyzing: Differentiate between the formulas of ionic and covalent compounds.
Evaluating: Discuss the relationship between the formula of a compound and the structure of its atoms.
