Electronic Structure, Bonding and The Periodic Table
Unit test Review for HChem
NOTE: You will need the periodic table that shows electronegativity values that is printed on the back of this unit’s objective sheet for this test.
What to study: all notes for this unit; sheet that accompanied the video, “The Periodic Table”;
“The Periodic Table” (study guide); Summary of Trends in the Periodic Table (homework assignment); Labs: “Covalent Compounds”; “Properties of Metals/Nonmetals”; Information sheet on Writing Chemical Formulas and Naming Chemical Compounds.
Concepts: Electronic structure: Be able to write/interpret electron configurations for any element; use the electron configuration and/or the group number to predict valence electrons and/or oxidation number. Predict the location of an element on the periodic table by looking at its electron configuration. Understand the principle energy (quantum) levels and sublevels of the electron cloud and how they relate to position on the periodic table. Be able to write/interpret Lewis dot notation (for elements) and Lewis Dot Structures (for compounds) showing electron arrangement; Know why the Noble gases are inert.
Bonding: Know the types of bonds (ionic, nonpolar covalent and poplar covalent); be able to predict bond type using electronegativity differences and/or the nature of the elements that are making the bond (metal – nonmetal or nonmetal-nonmetal); Be certain you understand the meaning of the term electronegativity. Know why elements bond (recall octet rule); Know the general properties of ionic and covalent bonded compounds (differences in melting point, boiling point, solubility in water, phase at room temp, electrical conductivity).
Periodic Table: Know the general trends (down a group and across a period) for these properties of elements: electronegativity; ionization energy; reactivity (for metals); atomic size.
Know the general location of the metals, nonmetals and metalloids (semimetals) on the table; Know how the modern periodic table is arranged (by atomic number); Know the names of these groups: 1, 2, 3-12, 17 and 18.
