Alloy
A mixture of 2 or more elements, at least one of which is a metal
Covalent bond
The bond between 2 atoms that share one or more pairs of electrons
Covalent bonding
The attraction between 2 atoms that share one or more pairs of electrons
Delocalised electron
Bonding electron that is no longer associated with any one particular atom
Dot and cross diagram
A drawing to show only the arrangement of outer shell electrons of the atoms or ions in a substance
Fullerene
Form of the element carbon that can exist as large cage like structures, based on hexagonal rings of carbon atoms
Gases
Substances that have no fixed shape or volume and can be compressed easily
Giant covalent structure
A huge 3d network of covalently bonded atoms
Giant lattice
A huge network of atoms or ions
Intermolecular forces
The attraction between the individual molecules in a covalently bonded substance
Ionic bond
The electrostatic force of attraction between positively and negatively charged ions
Particle theory
A theory that explains the properties of solids, liquids and gases based on the fact that all matter is made from tiny particles. It describes the movement of particles and the distance between them
Polymer
A substance made from very large molecules made up of many repeating untis
