Unit 2.4-Structure of Metals and Alloys
Apply Coulomb’s Law and electronic structure to compare
electronegativity values for two elements.
-
Explain why Fluorine (F) is more electronegative than Bromine (Br)
Classify a bond as ionic, non-polar covalent, polar covalent, or
metallic using periodic trends.
- Which is ionic MgO, BF₃, Cu, O₂?
- Which is polar covalent MgO, BF₃, Cu, O₂?
- Which is mettalic MgO, BF₃, Cu, O₂?
- Which is non-polar covalent MgO, BF₃, Cu, O₂?
Assign partial charges to atoms in a bond based on electronegativity.
-
Assign the partial charges to the polar covalent molecule carbon
monoxide (CO)
Recognize that ionic and covalent bonds exist on a continuum, with polar
covalent bonds in between.
-
Think of a covalent molecule that has greater ionic character than
nitrogen monoxide (NO)?
-
Think of a covalent molecules that has lesser ionic character than.
nitrogen monoxide (NO)?
Describe the nature of bonding in terms of electron donation,
acceptance, sharing, or delocalization.
-
Match ionic, covalent, metallic to the descriptors:
accepting/donating, sharing, and delocalization.
