3.01 Analyze periodic trends in chemical properties and use the periodic table to predict properties of elements. ** PERIODIC TRENDS, including… ** ** Electronegativity **
 * Groups (families).
 * Periods.
 * Representative elements (main group) and transition elements.
 * Electron configuration and energy levels.
 * Ionization energy.
 * Atomic and ionic radii.
 * Electronegativity.
 * Using the Periodic Table, students should be able to: **
 * Groups (families) **
 * Identify groups as vertical columns on the periodic table.
 * Know that main group elements in the same group have similar properties, the same number of valence electrons, and the same oxidation number.
 * Understand that reactivity increases as you go down within a group for metals and decreases for nonmetals.
 * Periods **
 * Identify periods as horizontal rows on the periodic table.
 * Representative elements (main group) and transition elements **
 * Identify representative (main group) elements as A groups __or__ as groups 1, 2, 13-18.
 * Identify alkali metals, alkaline earth metals, halogens, and noble gases based on location on periodic table.
 * Identify transition elements as B groups __or__ as groups 3-12.
 * Electron configuration and energy levels **
 * Write electron configurations, including noble gas abbreviations (no exceptions to the general rules). Included here are extended arrangements showing electrons in orbitals.
 * Identify s, p, d, and f blocks on Periodic Table.
 * Identify an element based on its electron configuration. (Students should be able to identify elements which follow the general rules, not necessarily those which are exceptions.)
 * Determine the number of valence electrons from electron configurations.
 * Predict the number of electrons lost or gained and the oxidation number based on the electron configuration of an atom.
 * Ionization energy **
 * Define ionization energy.
 * Know group and period general trends for ionization energy.
 * Apply trends to arrange elements in order of increasing or decreasing ionization energy.
 * Explain the reasoning behind the trend.
 * Atomic and ionic radii **
 * Define atomic radius and ionic radius.
 * Know group and period general trends for atomic radius.
 * Apply trends to arrange elements in order of increasing or decreasing atomic radius.
 * Compare cation radius to neutral atom. Compare anion radius to neutral atom.
 * Explain the reasoning behind the trend.
 * Define electronegativity.
 * Know group and period general trends for electronegativity.
 * Apply trends to arrange elements in order of increasing or decreasing electronegativity.
 * Explain the reasoning behind the trend.
 * Use differences in electronegativity to predict bond type (ionic, polar covalent, and nonpolar covalent).

__Periodic Trends Project__
Create a Period Table showing the following trends:
 * 1) Atomic Radius
 * 2) Ionic Radius
 * 3) Reactivity
 * 4) Electronegativity
 * 5) Ionization Energy
 * 6) Metallic Property

Remember... creativity and neatness does count!
