To help students with visual impairments to memorize the major polyatomic ions
An ion is an atom or group of atoms that has a charge because of the loss or gain of electrons. A polyatomic ion is an ion that consists of at least two different elements. Polyatomic ions are common ingredients in many foods and household products. Phosphate, nitrate, sulfate, and sulfite are just a few examples. Memorizing the chemical formulas and names for the major polyatomic ions can assist students in writing more complex expressions in chemistry. Playing a game is an enjoyable way to work on memorization skills.
