Study Notes
Types of Bonding
- Atoms strive to achieve a noble gas configuration by sharing or transferring electrons to achieve maximal stability, resulting in strong "primary" bonding.
Primary Bonding
-
Ionic Bonding:
-
Results from the transfer of electrons between atoms, resulting in the formation of ions with opposite charges.
-
Strong Coulomb interaction between positively and negatively charged ions.
-
Example: Na+Cl-
-
Covalent Bonding:
-
Involves sharing of electrons between atoms to saturate their valency.
-
Electrons are localized between neighboring atoms, forming directional bonds.
-
Example: H2 molecule
-
Metallic Bonding:
-
Involves the formation of an "electron sea" that binds positively charged ions together.
-
Non-directional bonding, allowing for plastic deformation.
-
Examples: Cu, Al, Au, Ag
Secondary Bonding
- Weak bonding resulting from the interaction of atomic or molecular dipoles.
- Types of secondary bonding:
- Fluctuating Induced Dipole (inert gases, H2, Cl2)
- Permanent Dipole Bonds (polar molecules -H2O, HCl)
- Polar molecule-induced dipole bonds
Bonding in Real Materials
- Metals: Metallic bonding
- Ceramics: Ionic and Covalent bonding
- Polymers: Covalent and Secondary bonding
- Semiconductors: Covalent or Covalent/Ionic bonding
