What you can learn
- Covalent bonds share electrons; ionic bonds transfer them.
- A small electronegativity difference gives nonpolar covalent, a medium one gives polar covalent, and a large one gives ionic.
- Ionic compounds form crystal lattices, not separate molecules.
Frequently asked questions
How do I tell if a bond is ionic or covalent?
Look at the electronegativity difference: below about 0.4 is nonpolar covalent, 0.4 to 1.7 is polar covalent, and above about 1.7 is ionic.
Why do ionic compounds conduct electricity when dissolved?
Their ions are free to move in solution and carry charge.
