Department: ___Science__________________ Teacher: ____Davis_________________
Course: ____Honors Chemistry________________________
Topic / Theme: ___Bonding and Molecular Geometry_______________________________________
Essential Question:
What are the types of chemical bonds and
how do they form?
How can you determine the shapes of small
molecules?
Key Questions:
How does electronegativity help determine what type of
bond two atoms will form? What types of elements
tend to form ionic bonds? What happens to the valence
shells of atoms when they become ions and form ionic
bonds? What happens to the valence electrons and
valence shells of atoms when they form covalent bonds?
How does a polar covalent bond differ from a non-polar
covalent bond? How can Lewis dot diagrams be used to
represent ionic and covalent compounds? How can
Lewis Structures be used to determine the shape of
small molecules and the hybridization of the central
atom? How can you determine if a molecule is polar?
