Atomic Model Worksheet

The document provides a worksheet about the superheroes of the atomic model - Democritus, Dalton, Thomson, and Rutherford - asking for their key discoveries and the timing and impact of those discoveries in developing the current atomic model. It asks for details about each scientist's contribution, including Democritus describing atoms, Dalton's atomic theory, Thomson discovering the electron and disproving part of Dalton's theory, and Rutherford deducing the nuclear structure through his gold foil experiment.
