Bonding, structure and properties of substances GapFill

Substances can be in one of three states of matter, which are called solid, liquid and  aquasteamgasparticle. Substances are different states at different  temperaturestimesvoltagescharges. The states of matter can also be given symbols, which are  (so), (li), (ga) and (aq)(s), (l), (g) and (aq)(so), (li), (pa) and (aq)[s], [l], [m] and [aq].

Ionic compounds have high  conductivityconcentrationsmelting pointsdensities due to strong electrostatic  reactionsproductsattractionscharges between oppositely charged ions.

Small molecules have very weak  latticesmetallic attractionsintermolecular forcesmolecular bonds and so they melt and boil at very low temperatures.

Polymers are large molecules with  layeredcovalentionicliquid bonds between atoms. Polymers have relatively strong intermolecular forces, so are mostly  whitesolidchargedconductive at room temperature.

Large, regular structures of covalently bonded atoms are called  huge covalent compoundsionic latticesgiga-covalent formationsgiant covalent structures. Diamond and  silicawaterozoneammonia are examples.

In metals, atoms arrange into  cubeslayerssphereslines which can slide over each other when the metal is bent. Mixtures of metals, called  bronzealloyssteelcrystals, have distorted layers, and so are  softershinierharderduller than pure metals.
