level 2 chemistry bonding and structure

molecular solids are made up of

molecules

ionic solids are made up of

cations and anions

metallic solids are made up of

atoms (cations and electrons)

covalent network solids are made up of

atoms

molecular solid attractive forces are

weak intermolecular

ionic solid attractive forces are

ionic bonds (positive ions to negative ions)

metallic solid attractive forces are

metallic bonds (cations to electrons)

covalent network solid attractive forces are

covalent bonds

electrical conductivity of metallic solids

good because the delocalized electrons are able to move when a voltage is applied

melting / boiling point of metallic solids

relatively high as energy required to break the strong metallic bonds requires high temperatures

solubility of metallic solids

non-soluble as metallic bond is stronger than the particles in the metal and any other solvent particles

properties of metallic solids

malleable, ductile, some are hard some are soft

electrical conductivity of ionic solids

solid - non conductor

liquid
