Atoms Test Study Guide Structure of an Atom What is an atom? What makes up an atom? (What are the three sub-atomic particles?) Check the box under the particle if the statement on the left is true for that particle. Proton Electron Neutron Particle with a charge Determines identity of an atom Particle in the nucleus Two particles with about the same mass Determines an atom's chemical properties Atomic Theory and Modeling What is Dalton's Atomic Theory? Models of Atoms Scientist/Model Name Model Diagram/Information Democritus Dalton Thompson/Plum Pudding Model Rutherford Bohr Heisenberg, Schroedinger/Modern Model Why was the model proposed by Democritus ignored or rejected? How has the model changed? Why has the model changed? What is kinetic theory? How does kinetic theory relate to atoms and phase change of matter? How is energy related to atoms, the atomic structure, and models of atoms? The Periodic Table of the Elements Know the names and symbols of the first 20 elements. What are the rows of the Periodic Table called? What do they show? What are the columns of the Periodic Table called? What do they show? How are elements in the columns related? Where are the metals located on the Periodic Table? Where are the nonmetals located on the Periodic Table? What are the elements between the metals and nonmetals called? Where is the atomic number on the Periodic Table? What does it represent? Where is the mass number on the Periodic Table? What does it represent? How do you find the number of protons? How do you find the number of electrons? How do you find the number of neutrons? What is an ion? What is a positive ion called? Does a positive ion gain or lose electrons? What is a negative ion called? Does a negative ion gain or lose electrons? What are valence electrons? Why are they important? What is an isotope? How is the atomic mass calculated? (Why is it a decimal instead of a whole number?) What is a mole? How is a mole useful? How do you know the mass of one mole of an element?
