How do ionic and covalent compounds compare?
• Ionic compounds make _____________________
•
Covalent compounds make ____________________
•
The strong attractions among positive and negative ions in an ionic compound
result in a strong, three-dimensional ____________________ structure that is
____________________, ____________________, and must be heated to high
temperatures to melt.
•
Covalent molecules do not have strong attractions, so they form
____________________, ____________________, or relatively
____________________ solids
•
The attractive forces between molecules of a covalent compound are weak
because the molecules themselves have no ____________________.
•
Ionic compounds are ______________________, compounds that conduct
electricity when melted or dissolved in water.
•
Covalent compounds are ____________________ conductors of electricity.
