Structures and Properties of solids

Solids

Materials with closely packed particles and definite shape.

Ionic Crystals

Lattice structure held by strong ionic bonds.

Solids

Ionic Crystals

Lattice structure held by strong ionic bonds.

Metallic Crystals

Positively charged ions surrounded by delocalized electrons.

Molecular Crystals

3-D arrangement of molecules with weak intermolecular forces.

Covalent Network Crystals

Macromolecules with atoms bonded by covalent bonds.

Amorphous Solids

Randomly arranged solids without distinct melting points.

High Melting Points

Characteristic of ionic and covalent network crystals.

Conduct Electricity

Ability of ionic liquids and metallic solids.

Malleable

Ability of metals to be shaped without breaking.

Ductile

Capability of metals to be drawn into wires.

Lustrous

Shiny appearance due to light interaction with electrons.

Hardness

Resistance to deformation or scratching in solids.

London Dispersion Forces

Weak intermolecular forces present in molecular crystals.

Hydrogen Bonding

Strong intermolecular attraction involving hydrogen atoms.

Polar Molecules

Molecules with uneven distribution of charge.

Non-Polar Molecules

Molecules with even distribution of charge.

Graphite

2-D covalent network solid with layered structure.

Diamond

3-D covalent network solid known for hardness.

Asbestos

1-D covalent network solid used in insulation.

Allotropes

Different physical forms of the same element.

Soft Solids

Characteristic of molecular crystals due to weak forces.

Room Temperature State

Solid, liquid, or gas depending on intermolecular forces.

Electrostatic Attractions

Forces holding metallic nuclei together.
