AP Chemistry / Unit 2: Compound Structure and Properties
2.1 Types of Chemical Bonds
Notes
- Nonpolar covalent: electrons shared equally (similar electronegativity).
- Polar covalent: shared unequally.
- Ionic: metal and nonmetal, electrons transferred.
- Metallic: a sea of delocalized electrons.
Practice
The bond in $\mathrm{HCl}$ is:
Cl is more electronegative than H.
Which compound is ionic?
Metal and nonmetal.
In a polar bond, the more electronegative atom gets:
It pulls the electrons closer.
