Atomic Theory Timeline

Build an atomic theory timeline! Learn about scientists and atomic models.

Watch the video about scientists and the theories that they have developed over time about matter and the atom. TedEd Atomic Theory: A Brief History create and edit presentations online, for free. Cut out the scientists' names, information boxes, pictures, atomic models, and analogies, and organize them by date Read the information about the scientists in the Atomic Theory Timeline information packet. create and edit presentations online, for free. On the attached Google Slide, design a timeline that includes dates from 400 B.C. to the later 20tth century. Your timeline can be a straight line, or more of a journey. Your time line does not have to be digital, but can take any form you want. Atomic Theory Timeline Once you've finished your timeline, answer the following eight questions: Who discovered the electron Dalton Thomson Rutherford Bohr What did Rutherford discover in his experiment? nucleus electrons neutrons In which model are atoms imagined as tiny balls? Dalton Thomson Rutherford Bohr Who proposed a model with electrons moving in specific layers? Dalton Thomson Rutherford Bohr What does atom mean? small visible indivisible particle Who is "responsible" for the 2000-year "Death of Chemistry"? Aristotle Democritus Thomson Dalton Rutherford's "gold foil" experiment using alpha particle scattering concluded that: the center of the atom is empty atomic mass is spread over the whole atom the center of the atom has a negative charge most of the atom is empty In which model are atoms imagined as the solar system? Dalton Thomson Rutherford Bohr
