Name: _____________History of the Atom Timeline Assignment /20 Read the information package to understand how the model of the atom has developed over the years. Create a timeline demonstrating your understanding of the progression. The timeline can be straight or curvy but it must be in order, with dates. You may cut and paste images below or draw your own. Your timeline must include the following:TitleThe following people:DemocritusDaltonRutherfordAristotleThomsonBohrSchrodinger, Heisenberg, Einstein and other scientistsFor each scientist include a description of each theory,For each scientist include a model of each theoryFor each scientist include an analogy for each theoryWhen you are done, answer and hand in the following questions.QuestionsWho discovered the electron?Daltonc) RutherfordThomsond) BohrWhat did Rutherford discover in his experiment?NucleusElectronsNeutronsIn which model are atoms imagined as tiny balls?Daltonc) RutherfordThomsond) BohrWho proposed a model with electrons moving in specific layers?Daltonc) RutherfordThomsond) BohrWhat does “atom” mean? Small c) indivisibleVisibled) particleWho is ‘responsible’ for the 2000-year “Death of Chemistry”?Aristotlec) ThomsonDemocritusd) DaltonRutherford’s “Gold-foil” experiment sing alpha particles scattering concluded that The center of the atom is emptyAtomic mass is spread over the whole atomThe center of the atoms has a negative chargeMost of the atom is empty spaceIn which model are atoms imagined as a solar system?Daltonc) RutherfordThomsond) BohrHow you will be assessed: Having all the content required and in the correct order (8)Well organized and easy to interpret. (2) Timeline is aesthetically pleasing.
