chem solids properties!

ionic substance definition

attraction between + and - atoms

ionic substance properties

high melting point, soluble in very polar substances, high conductivity in liquids/solutions, always solids at room temp due to strong electrostatic force of attraction, very high melting point due to strong bonds, hard, brittle, transparent

polar molecular definition

polar covalent bonds in a molecule - dipole-dipole / hydrogen bonds between molecules

polar molecular properties

low conductivity

non-polar molecular definition

polar/non-polar covalent bonds, forming non-polar molecules, held together by LDF

non-polar molecular properties

very low melting/boiling point, very low conductivity

network solid definition

atomic crystals, covalent solids. Covalent bonds linking all units.

network solid characteristics

metalloid compounds, hard plastics, high melting/boiling point, not soluble, very hard/tight structure

metallic definition

“free” valence shell electrons, shared by all metal atom kernels

metallic characteristics

very high conductivity (sea of electrons), very shiny/malleable, never soluble in water, conducts in solid state due to mobility of sea of electrons from one end to the other
