Chapter 5: Atomic Structure and The Periodic Table Study Guide 5.0 (Not in textbook-‐ refer to notes and handouts) Describe some of the experiments that led to the current atomic theory (cathode ray tube, and gold foil). Compare the different models of the atom (Dalton, Thomson, Rutherford, Bohr, Modern) Explain how the atomic theory has changed over time. Identify the contributions of Democritus, Dalton, Thomson, Rutherford, Bohr, Schrodinger and Heisenberg 5.1 Be able to label an atom diagram Know the charge and relative mass of the electron, proton, and neutron Define atomic number, atomic mass number, and isotopes. Use atomic number and mass number to determine the amount of protons, neutrons, and electrons in an atom. 5.2 Be able to describe the process that Mendeleev used to develop the first periodic table. Be familiar with the difference between his arrangement and the current arrangement. Describe how elements are arranged in the current periodic table. Be able to read the periodic table and find the atomic number, element name, element symbol, and atomic mass of an element. Describe the difference between a period and a group. Be familiar with the density and atomic size trends in the periodic table.

Explain why elements in a group often have similar properties. Describe the properties of the elements in the families of the periodic table: alkali metals, alkaline-‐earth metals, transition metals, lanthanides and actinides, BCNO, halogens, and noble gases. Be able to explain why hydrogen “stands alone” on the periodic table. Describe how a radioactive element can change into another element and be able to identify elements that are radioactive. Understand the concept of half-‐life. Math in Science Be able to express numbers in scientific notation. Be able to calculate the atomic mass of an element Amy Kenny-Whritenour Friday, May 9, 2014 2:57:58 PM ET
