Two worksheets with varying levels of difficulty where students use a paperclip and pencil to create a game spinner. The spinner selects the positive and negative ion students use to write a formula and name as practice.
Worksheet #1 contains both binary and polyatomic ions, and includes the charges written for the students
Worksheet #2 includes binary, polyatomic ions, and transition metals, and forces students to look up the charges from their periodic table and polyatomic ion chart.
Good for in class practice after direct instruction, or as a homework assignment.
