Study Notes
Bonding in Solids
- Metals have delocalized bonding, where electrons are free to move throughout the metal lattice.
- Carbon structures like graphite are not close-packed because of the way carbon atoms bond with each other; they form flat, two-dimensional layers with weak interlayer forces.
Ionic Solids
- Ionic solids are made up of cations (positively charged ions) and anions (negatively charged ions).
- When ions become charged, cations lose electrons to become positively charged, while anions gain electrons to become negatively charged.
- The size of cations and anions changes when they become charged, with cations typically decreasing in size and anions increasing in size.
Characteristics of Bonding
- Ionic solids are characterized by electrostatic attraction between oppositely charged ions.
- Metallic bonding is characterized by the delocalization of electrons throughout the metal lattice, allowing for electrical conductivity.
- The type of bonding represented by carbon in graphite, diamond, nanotubes, and fullerenes is covalent bonding.
Additional Notes
- The main characteristic of ionic solids is the electrostatic attraction between oppositely charged ions.
- The main characteristic of metallic bonding is the delocalization of electrons, which allows for electrical conductivity and malleability.
