1. Describe why and how atoms combine.
A.
B.
C.
D.
State that atoms combine to achieve greater stability, as evidenced by a complete
outer shell. (REVIEW)
Use the periodic table to predict the number of valence electrons and likely charge
of elements in the s and p blocks. (REVIEW)
Explain how the octet rule applies to atoms of metallic and nonmetallic elements
(REVIEW)
Identify the type of bonding (nonpolar covalent, polar covalent, ionic, metallic)
between two elements given their electronegativities and/or their location on the
periodic table.
2. Compare and contrast ionic and covalent compounds
A.
B.
C.
D.
E.
F.
3.
Differentiate among properties of ionic and covalent (polar and nonpolar)
compounds (melting/boiling point, solubility, conductivity)
Relate the properties of ionic and covalent (polar and nonpolar) compounds
(melting/boiling point, solubility, conductivity) to their bonding / structure.
Describe how electrons are shared to form covalent bonds and how electron dot
structures represent shared and unshared electrons.
Describe how atoms form double or triple covalent bonds
Describe how electrons are transferred to form cations (positive) and anions
(negative). (REVIEW)
Describe how the attraction between oppositely charged ions results in an ionic
bond. (REVIEW)
Describe the bonding in metals and relate it to the properties of metals.
A.
B.
C.
Describe the model of a metallic bond, including the valence electrons and the
metal atom ‘core’ (kernel).
Relate the properties of metals…(conductivity, luster, malleability, ductility) to their
bonding / structure.
Define ‘alloy’ and explain the importance of alloys.
4. Relate how molecular shape and polarity relate to properties of covalent
compounds.
A.
Use models to describe and explain the structure of a molecule.
[molecular formulas, 3-D models, structural formulas, Lewis dot structures,
molecular shapes]
B.
Determine bond polarity within a molecule and use this information… along with
molecular shape… to determine if a molecule is polar or nonpolar.
Describe the various intermolecular forces, including van der Waals, dipole/dipole,
and hydrogen bonding. Compare the relative strengths of these intermolecular
forces – and compare them to the relative strengths of intramolecular forces (i.e.
covalent bonds).
Explain what makes ‘sticky stuff’… what makes stuff sticky?
Discuss a particular application of this idea… from teacher provided resources
C.
D.
E.
Describe a network solid and explain how this type of covalent substance differs
from molecular covalent substance
