Key Learning:
Electron structure of an atom determines the bond type and bond properties of the compounds it forms.
Unit Essential Question(s):
Concept: Ionic Bonding Apply the rule that gaining or losing electrons determines the oxidation state for an element.
Depict the electron configuration for an ion.
Write the formula for a compound when given the name.
Name the compound when given the formula.
Concept: Covalent Bonding Construct electron dot (Lewis) diagrams for molecules.
Write the formula for a compound when given the name.
Name the compound when given the formula.
Suggested Extended Thinking Strategy: Classifying/Categorizing
Concept: Determination of Bonding Types Compare and contrast the properties of ionic and covalent bonds.
Predict the type of bonding between two elements based on trends (ionization energies, electronegativity).
Predict the ionic/covalent character of compounds from electronegativity trends.
Suggested Extended Thinking Strategy: Compare/Contrast
Lesson Essential Question(s):How does electron structure relate to ion formation?
