Study Notes
Chemical Bonds
- A chemical bond is a lasting attraction between atoms or ions that enables the formation of molecules, crystals, and other structures.
Types of Bonds
- Ionic bonds: result from the electrostatic force between oppositely charged ions
- Covalent bonds: result from the sharing of electrons
- Metallic bonds, ionic bonds, and covalent bonds: classified as "strong bonds" or "primary bonds"
- Dipole-dipole interactions, London dispersion force, and hydrogen bonding: classified as "weak bonds" or "secondary bonds"
Electrostatic Forces
- Opposite electric charges attract: negatively charged electrons surrounding the nucleus and positively charged protons within a nucleus attract each other
Shared Electrons
- Electrons shared between two nuclei will be attracted to both of them
- "Constructive quantum mechanical wavefunction interference" stabilizes the paired nuclei
Bond Distance
- Bonded nuclei maintain an optimal distance (the bond distance) balancing attractive and repulsive forces
