• 1/8 of each particle is used

• only the corner of the cell

• only 1 particles

• A single ball surrounded by 8 particles

• again 1/8th from the corner of each particle and 1 center particle

• 2 particles

Face centered cubic

• 4 particles

molecular solids

made of molocules

ionic solids

are solids who have particles and ions

atomic solids

solids have particles and atoms

types of atomic solids

• Non bonding solids: held together via dispersion force

• Metallic atomic solids: Heald together with metal bonds

• Network covalent atomic solid: a chemical substance where individual atoms are linked together by a continuous, giant network of strong covalent bonds

Solute

Being dissolved

Solvent
