who present the modern theory
Answers
Answer:
To begin your exploration of the modern atomic theory, go to and read each section of Electrons in Atoms, a chronological timeline marking milestones from 1897 to the present in the advancement of atomism since the electron.
Use the information from this resource to help you complete the word match on the Electrons in Atoms student sheet.
Now you should continue your investigation by reading A Summary of Particle Physics, which briefly describes the evolution of particle physics from the early 1900s to the present. As you go through this resource, think about your answers to these questions, which you can record on your Particle Physics student sheet:
➽
J.J. Thomson ✅
The History of the Atom :-
➔1: The Ancient Greeks examines the ancient Greeks’ theories about the atom.
➔2: Dalton explores early milestones in atomic theory and the role of John Dalton.
➔3: The Periodic Table reviews the early development of the periodic table and its impact on atomic thought.
➔4: J.J. Thomson analyzes the evolution of modern ideas on the inner workings of atoms and J.J. Thomson’s contributions. This lesson investigates the development of modern atomic theory.
➠Thomson’s purpose in experimenting with cathode rays and electrical currents inside glass tubes, point out that Thomson was the first scientist highlighted in this history series to use advanced instrumentation in the atomic discovery process. In this final lesson, they will learn of the greater role that bigger and more advanced instruments like accelerators have taken in advancing the study of modern atomic theory.
