Periodic Table Basics Make-Up Test Standards covered: (these are not questions.) Note: since some of these standards “give the answer,” they will not be written out in detail on the real test. IX. Atomic and molecular structure: The periodic table displays the elements in increasing atomic number and shows how periodicity of the physical and chemical properties of the elements relates to atomic structure. As a basis for understanding this concept: A. relate the position of an element in the periodic table to its atomic number and atomic mass. B. use the periodic table to identify: 1. metals 2. semimetals 3. non-metals 4. halogens. 5. noble gases C. use the periodic table to identify: 1. alkali metals 2. alkaline earth metals 3. transition metals D. use the periodic table to determine the number of electrons available for bonding. F.* use the periodic table to identify: 1. the lanthanide elements 2. actinide elements H.*identify or explain the experimental basis for: 1. Thomson 2. Rutherford Fill in the following table: (IX A) Name of element Symbol Atomic number sodium Sr cadmium 15 Identify each element as: (IX B1-3) A. metals B. semimetals (used only once) C. non-metals _____1. B _____6. Se _____2. Ag _____7. Na _____3. Br _____8. Sr _____4. Te _____9. Cu _____5. Cl _____10. Ni Atomic mass (as written on the periodic table) Identify each element as : (IX B 4-5, C 1-3) D. halogens. E. noble gases F. alkali metals G. alkaline earth metals H. transition metals _____1. Cl _____6. Au _____2. Co _____7. Mg _____3. Ba _____8. Kr _____4. Br _____9. K _____5. Rb _____10. Ar D. use the periodic table to determine the number of electrons available for bonding. (IX D) Element or symbol How many electrons are available for bonding? (aka valence electrons) Element or symbol Cs Ca F Na C Al As Fr Si Se How many electrons are available for bonding? (aka valence electrons) use the periodic table to identify each element as belonging to one of these groups: (IX F 1 - 2) I. the lanthanide elements J. actinide elements ____1. Pr ____2. Er ____3. Cf ____4. Cm ____5. No Std IX H 1: Explain what JJ Thompson figured out. You may draw and label a picture if that helps explain your answer. Explain what E. Rutherford figured out. You may draw and label a picture if that helps explain your answer. (IX H2)
