From models to materials - bonding models Flashcards
What are the three types of chemical bonding?
Ionic, covalent, and metallic.
What do bonding types explain?
Chemical and physical properties of substances.
What is a limitation of bonding models?
Inaccuracies that arise from oversimplification.
True or False: Aluminium chloride behaves like an ionic compound.
False.
What evidence suggests that bonding type cannot be easily compartmentalized?
The existence of polar covalent bonds.
How is bonding best thought of?
As a continuum of the three different bonding types.
What shapes the bonding triangle?
Electronegativity difference and average electronegativity.
What is the symbol for electronegativity?
The Greek letter (chi) χ.
How is the average electronegativity of two elements A and B calculated?
χ = (χ_A + χ_B) / 2.
Where would elements with zero difference in electronegativity be found?
Along the x-axis.
Where are ionic compounds located in the bonding triangle?
Top center part or apex.
Where are covalent compounds located in the bonding triangle?
Bottom right.
Where are polar covalent compounds found in the bonding triangle?
In the zone between ionic and covalent.
