Types of substance GapFill

There are three main types of strong chemical bonding:

•  polymeric bondingatomic bondingionic bondingcovalent bondingtransition bondingmetallic bonding, which occurs between a metal and a non-metal;
•  polymeric bondingionic bondingtransition bondingcovalent bondingnon-metallic bondingatomic bonding, which occurs between non-metals, either in simple molecular or giant covalent bonding;
•  covalent bondingpolymeric bondingionic bondingperiodic bondingtransition bondingmetallic bonding, which occurs between metals

Ionic compounds have high  positivityconcentrationsconductivitymelting pointsdensitiesentropy due to strong electrostatic  attractionslayersrepulsionschargesreactionsproducts between oppositely charged ions.

Small molecules have very weak  intermolecular forcesmetallic attractionslatticesdelocalised electronsmolecular bondsionic interactions and so they melt and boil at very low temperatures.

Polymers are large molecules made of chains of  metallically bonded metal atomsionically bonded carbon atomsionically bonded hydrogen and oxygen atomscovalently bonded silicon atomscovalently bonded oxygen atomscovalently bonded carbon atoms. Polymers have relatively strong intermolecular forces, so are mostly  whitechargedsolidfrozenlocalisedconductive at room temperature.
