Test Topics

  • Know the difference between covalent, ionic, and metallic bonds.

  • Know the definition of electronegativity

  • Know the trends for electron affinity, electronegativity, and atomic radius on the periodic table. 

  • Be able to determine which out of 2 atoms is more electronegative.

  • Know that Fluorine is the most electronegative element and why.

  • Be able to draw molecular structures, determine the molecular shape, calculate the electronegativity difference, name the bond type, and identify the hybridization. 

What needs to be memorized

  • Molecular geometry

    • Linear

    • Bent

    • Trigonal planar

    • Trigonal pyramidal

    • Tetrahedral 

  • Scale for different types of bonds

    • Less that 0.3 = Non-polar

    • 0.31-1.8 = Polar

    • Greater than 1.8 = Ionic

  • Hybridization table 

    • Atoms + Lone Pairs on central atom
