X Unit 11 Test Study Guide: The Periodic Table Friday, March 4th 65 points total Part I: Multiple Choice (20 questions @ 1 point each = 20 points total) Topics: o Vocabulary Group, period, metal, nonmetal, metalloid, valence electron, periodic, cation, anion, etc. Know properties of metals vs. nonmetals o Periodic trends Be able to apply trends for electronegativity, ionization energy, atomic radius, and metallic character to answer questions Know definitions of each of the properties as well! Understand what ionic radius is and how it relates back to the size of the original atom o History of the periodic table Know each scientist’s contribution to the development of the periodic table Scientists: Lavoisier, Dӧbereiner, Newlands, Mendeleev, Moseley o Characteristics of the periodic table (groups, periods, etc.) Know the 4 groups we talked about specifically and characteristics of each group Know different areas of the periodic table such as: metal, nonmetal, metalloid, alkali metal, alkaline earth metal, halogen, noble gas, lanthanide series, actinide series, etc. Part II: Matching (6 terms, 6 points total) Be able to match the scientists we discussed in class with their major contribution(s) to the development of the periodic table Part III: Trends (12 questions, 16 points total) 4 questions: place four elements in order from lowest to highest for a given property using mathematical symbols ( < or > ) 8 questions: choose higher value for a given trend between two elements Part IV: Open-Ended Element Questions (4 questions, 18 points total) Fill in information about a given element based on where it is on the periodic table Part V: Short Answer (3 questions, 5 points total) Provide information about specific groups we mentioned in class (Groups 1, 2, 17, and 18) ***Study old homework questions, notes, warm up problems, and example problems to get a sense of the type of questions you will see!! Sample Review Problems: (answer on a separate piece of paper if needed) 1. Fill in the following information for the element astatine: a. Symbol: At b. Group #: 17 c. Group name: Halogens d. Period: 6 e. Metal, nonmetal, or metalloid: nonmetal 2. What is the trend for ionization energy? Explain why this trend behaves as it does? Ionization energy increases going up a group and across a period from left to right. The more electronegative an element is, the closer it can pull electrons. In addition, the smaller the radius of the atom, the closer the electrons are to the nucleus. This proximity results in an increased positive/negative attraction. It will take more energy to overcome these Coulombic attractions. Therefore, where the radius is small, the ionization energy is high. 3. What were the major contributions of Mendeleev, Seaborg, and Newlands to the development of the periodic table? See the notes packet!!! 4. Label the following properties as being either characteristic of a metal (M) or characteristic of a nonmetal (NM). _M__ shiny _NM__ brittle _M__ malleable _NM__ low melting points _M__ large atomic radius _NM__ form anions __M_ conduct electricity _NM_ very electronegative __M_ solid at room temp. 5. Write the name of the group that each characteristic below applies to: a. Inert noble gases b. Extremely reactive alkali metals (or halogens) c. Do not occur in nature on their own (always in a compound) alkali & alkaline earth metals d. Diatomic halogens e. Mixed phases at room temperature halogens 6. Why is the periodic table called the periodic table of elements? Properties repeat when arranged by increasing atomic number 7. (Fill in the blank) The ionic radius of the chloride ion (Cl-) would be _____larger______ than the radius of the chlorine atom from which it forms. 8. Place the elements in order of increasing metallic character using < or > symbols: P, N, V, Fe N < P < Fe < V (increases down and to the left) 9. Why do elements in the same group have similar properties and characteristics? Same # of valence e10. (Fill in the blank) Going from left to right across a period, the radius ______decreases_____. Going down a group from top to bottom, the radius ___________increases______.
