Study Notes
Solids and Their Characteristics
- A solid with a characteristic heat of fusion is an amorphous solid.
Bonding in Solids
- Atoms, ions, and molecules are held together in solids by intermolecular forces or electrostatic forces.
Solids vs. Gases
- Solids are distinguished from gases in that they have a fixed density and are incompressible, whereas gases have varying density and are compressible.
Crystalline Solids
- The defining characteristic of a crystalline solid is that it has a repeating pattern of atoms, ions, or molecules arranged in a crystal lattice.
Ideal Gases
- The intermolecular forces between gas molecules disappear completely when a gas is ideal.
Test your knowledge of the fundamental concepts of solid state chemistry including synthesis, structure, bonding, reactivity, and physical properties of solids.
