Subatomic Particles

The Subatomic Particles Concept Builder challenges learners to use information regarding the number of protons, neutrons, and electrons within an atom in order to complete a table showing such data for a variety of isotopes. There are three scaffolded difficulty levels. In the Apprentice Difficulty Level, each of the particles are neutral atoms. In the Master DIfficulty Level, each of the particles are charged ions and the number of electrons is stated. In the Wizard Difficulty Level, each of the particles are ions and the location of the element in the periodic table must be used to determine the ion charge. Question-specific help is provided for each of the three difficulty levels. The built-in score-keeping makes this Concept Builder a perfect candidate for a classroom activity.
