There are three main types of strong chemical bonding:
- , which occurs between a metal and a non-metal;
- , which occurs between non-metals, either in simple molecular or giant covalent bonding;
- , which occurs between metals
Ionic compounds have high due to strong electrostatic between oppositely charged ions.
Small molecules have very weak and so they melt and boil at very low temperatures.
Polymers are large molecules made of chains of . Polymers have relatively strong intermolecular forces, so are mostly at room temperature.
Diamond and are examples of large, regular structures of covalently bonded atoms.
In metallic bonding, are surrounded by . Positive ions are electrostatically attracted to . The atoms arrange into which can slide over each other when the metal is bent. Many metals are good of electricity and heat due to their .
