The evolution of the periodic system the modern periodic table in 1904, working at cambridge, physicist j j thomson (who also discovered the electron) developed a model of the atom, paying close attention to the periodicity of the elements. Introduction to the history of the theory of evolution and the scientific concepts within evolution an introduction to the history and basic scientific concepts what was it that darwin introduced to our thinking, that was so compelling that, even today, the modern theory of evolution. Lesson plan: introducing the atom periodictablerosendigitalcom change or evolution of a system are critical elements of study have a student or students attempt to draw a model of an atom based on prior knowledge research or experimentation. Introduction to atoms, atomic theory, introducing chemistry, science, year 9 we generally regard dalton as the founder of modern atomic theory from which other theories have since developed the standard two-dimensional model of an atom is one where dots. The atomic model has changed over time for over two centuries, scientists have created different models of the atom as scientists have learned more and more about atoms, the atomic the modern model (1932-) work done since 1920 has changed the model it is impossible to.
