2. Determine how many atoms of each element are present in a chemical compound given its
chemical formula.
3. Recognize and categorize substances as ionic, covalent and metallic.
4. Write the correct formula for any neutral ionic compound given its chemical name and vice
versa.
5. Write the correct formula and name for binary inorganic covalent compound given its chemical
name and vice versa: Use prefixes mono-, di-, tri-, tetra-, pent-, hex- for inorganic compounds.
6. Write the correct formula and name for organic hydrocarbons- alkanes, alkenes, alkynes - given
its chemical name and vice versa: Use prefixes meth-, eth-, prop-, but-, pent-, hex-, hept-, oct-,
non-, dec- and suffixes –ane, -ene, and –yne.
7. Draw correct Lewis structures based on the number of valence electrons present on each atom.
8. Use electronegativity differences to determine whether or not bond dipoles exist within a
molecule.
9. Predict the shapes of molecules in which a central atom is bonded to surrounding atoms.
10. Predict whether a molecule is polar or non-polar based on its molecular shape and the polarity
of its bonds.
11. Form and identify possible isomers of molecules given a molecular formula.
12. Explain the behavior of delocalized electrons in a metallic substance.
13. Describe the different types of alloys.
