Honors Chemistry UNIT 3 All about the ATOM (Chapter 3 and Chapter 24: pg 684-699) How did early atomic theory evolve over time? How can an atom be changed and what are the results because of the change? How are math concepts used in chemistry? 1) Know: Definitions: - - - - - Aristotle Democritus Daltons Atomic Theory Thomson’s Atomic Theory o Cathode Ray Tube o Plum Pudding Model Millikan Rutherford o Gold Foil Experiment Bohr o Solar system model o Orbits Atomic Weight Isotope Atomic Number Ion Atom o Protons o Electrons o Neutrons Law of Conservation of Mass Nuclear Reactions o Alpha particle o Beta particle o Gamma rays o Positron o Nuclear Fission o Nuclear Fussion o Half-life Moles Avogadro’s Number Molar mass Particles Average atomic mass Understand: - What makes isotopes of the same element different The different types of radiation What average atomic mass represents How an atom becomes an ion. Nuclear reactions change an element. Be able to: - Compare the models of the atom Describe Dalton and Thompson’s early models of the atom and why parts of them are currently untrue. Explain Rutherford’s experiment and the significance of his observations. Explain the difference between an ion and an atom. Explain the difference between an isotope and atom Calculate the number of protons, electrons, and neutrons in an atom or ion given other appropriate information. Describe the structure of the atom. Write simple nuclear reactions and apply the law of conservation of mass Calculate half-life. Calculate mass remaining of an element after half-lifes have occurred. Use dimensional analysis to solve problems involving the relationships between grams, moles, particles, and liters.
