Academic Chemistry Atomic History Study Guide 1. Identify and explain the two ancient Greek theories of matter and who proposed each. a) b) 2. Identify and explain the three laws which caused doubt in Aristotle’s theory and provided evidence for Dalton’s Atomic Theory. Identify the person responsible for the statement of each law. a) b) c) 3. State the main ideas of Dalton’s Atomic Theory a) b) c) d) e) 4. Give two differences between the modern atomic theory and Dalton’s atomic theory. a) b) 5. Complete the following chart about the subatomic particles. Name Charge Location Mass Discoverer 6. Describe the following four experiments discussed in this unit. Please be sure to identify who was responsible for the development of each experiment. a) Vacuum tubes and the Electron b) Gold Foil Experiment and/or Gold Foil Experiment c) Oil Drop Experiment d) Franklin’s Kite Experiment 7. The two types of electrical charges identified by Franklin are ________________ & ____________________. 8. In 1839 Michael Faraday predicted that electricity was tied to the structure of the atom. It wasn’t until 1899 that his prediction was proven correct by ______________ _________________ when he discovered electrons, which were originally called ____________________ ________________. 9. In 1896 _______________ ____________________ accidentally discovered radiation but the three types; ______________, _____________, and ____________ were not identified until 1900 by ______________ _____________________. 10. A young engineer named ________________ ________________, who was killed in World War I, contributed greatly to science prior to his death by discovering the atomic number. 11. According to the laws of classical physics, a charged particle traveling on a curved path will lose energy. This would cause an electron to drop into the nucleus, which would destroy the atom. __________ _____________ proposed a new model of the atom that allowed electrons to circle the nucleus but only on specified paths (orbits) which for some reason were stable. The study of the motion of electrons lead to the development of a new branch of physics called _________________ mechanics. 12. One part of the Bohr model which is still in use today is the equation used to determine the number of electrons allowed in each energy level of the atom. Please state the equation and identify what each symbol represents. 13. The study of light lead to much advancement in Atomic structure. _____________ _______________ developed a formula, which can be used to calculate the amount of energy in any color of light. This equation built on the work of James Clerk Maxwell who theorized that light actually had wave characteristics. 14. One of the flaws in the Bohr model of the atom was pointed out by _____________ __________________ when he stated the Uncertainty Principle, which stated ______________________________________________________________________ ______. 15. The ground breaking work of Lise Meitner and Otto Frisch on nuclear fission, which eventually lead to the production of nuclear weapons, provided insight into the internal structure and composition of the atomic nucleus. Describe their discovery. 16. _______________ ____________________ developed mathematical equations which allowed super computers to calculate the probability of finding an electron at any point in space around the nucleus. When combined the points of high probablilty produced 3D shapes called __________________ where it was most likely you would find the electrons. 17. Two scientists, _____________ _______________ and ________________ ___________-________________ proposed a controversial theory in which the subatomic particles as we know them are actually composed of even smaller parts called ___________________. 18. We examined five models of Atoms in this unit. Identify, draw and explain the five models. a) Dalton’s Model b) Thomson’s Model c) Rutherford’s Model d) Bohr’s Model e) Quantum Mechanical Model(electron cloud model)
