With Thomson's discovery of neon atoms with differing masses, Dalton's postulate that all atoms of an element are identical and have the same mass faded away. This PowerPoint show, examines the history from Dalton to Chadwick regarding atomic mass, and highlights Chadwick's discovery of neutrons.

In addition, the PowerPoint defines terms such as mass number and atomic number, and explains how to use them to determine the number of neutrons.
