Atoms, Ions, and Isotopes Test Review This completed review sheet can be used on the test November 2, 2016 Definitions (or People) Atom Ion Isotope Proton Neutron Electron Valence electron Electron shell, orbital, electron cloud, energy level Atomic Number Mass Number Average Atomic Mass John Dalton John Dalton’s postulates J.J. Thompson Rutherford James Chadwick Bohr Cloud Model Bohr Model Electron Dot Diagram Gold Foil Experiment Cathode Ray Tube Neutral Charge (as in the state of an atom) Percent Abundance Chemical bond Cation Anion Atomic theory Nucleus Questions/ Practice Problems 1. Which of John Dalton’s postulates are still considered to be true today? 2. Which of John Dalton’s postulates are NOT considered to be true today? 3. What was discovered in the cathode ray tube experiment? 4. What did Ernest Rutherford’s gold foil experiment discover? (actually 4 discoveries) 5. What does APE MAN and Pretty Nice Mass stand for? 6. Describe the difference between atomic mass and mass number. 7. Be able to use symbolic isotopic notation (nuclear notation) or hyphenated notation. For example, write carbon -14 in nuclear notation. 8. Be able to determine the number of protons, neutrons, and electrons, in an atom. Example. If an element has 35 protons and a mass number of 80, how many electrons and neutrons does it have? Which element would this be? 9. Compare the masses and charges of protons, neutrons, and electrons. 10. What is the heaviest part of an atom? 11. What part of an atom takes up the most space or volume? 12. How many protons, electrons, and neutrons are in the following Boron -6, Boron -5, and 13 Carbon? 13. Draw a Bohr model of a neutrally charged carbon atom. 14. Draw an electron dot diagram of oxygen. 15.
