- 1Physical propertyAny property that is measurable, whose value describes a physical state or appearance
- 2Chemical propertyA characteristic of a substance that is observed during a chemical reaction
- 3Strong materialOne that cannot be easily broken
- 4Brittle materialOne that can be easily broken
- 5MalleableCan be bent, hammered or squashed into different shapes
- 6DuctileCan be stretched out into wires
- 7LustrousThe word used to describe the shiny appearance of metals when polished
- 8LatticeA structure consisting of a regular three dimensional pattern
- 9Structure of a metalLattice of positive ions, through which a 'sea' of electrons are free to move
- 10Metallic bondsThe electrostatic attraction between positive metal ions and negative delocalised electrons
- 11Ionic compoundsCompounds where the particles are joined by ionic bonds
- 12Ionic bondsBonds formed between oppositely charged particles
- 13IonA charged atom or group of atoms
- 14Octet ruleAtoms of main-group elements tend to combine in such a way that each atom has eight electrons in its valence shell, giving it the same electronic configuration as a noble gas
- 15Oxide\(O^{2-}\)
- 16Hydroxide\(OH^{-}\)
- 17Nitrate\(NO_3^{-}\)
- 18Chloride\(Cl^{-}\)
- 19Bromide\(Br^{-}\)
- 20Iodide\(I^{-}\)
- 21Sulfate\(SO_4^{2-}\)
- 22Carbonate\(CO_3^{2-}\)
- 23Phosphate\(PO_4^{3-}\)
- 24Unit cellThe simplest way of drawing the arrangement of ions in the lattice
- 25BondsForces of attraction that hold atoms together
- 26CationA positively charged ion
- 27AnionA negatively charged ion
- 28Electrostatic forcesForces of attraction between positively and negatively charged objects
- 29Covalent bondsInvolve the sharing of electrons between two or more atoms
- 30MoleculeThe structure that results when two or more atoms are joined together by a covalent bond Eg: Water
- 31AllotropesDifferent physical forms of the same substance Eg. Diamond and graphite are contain covalent bonds between carbon atoms
- 32Bonding in diamondCarbon atoms connected to four other carbon atoms by a strong covalent bond. This forms a tetrahedral unit cell. All four of carbon's electrons are involved in bonding with another carbon atom
- 33Bonding in graphiteLayers of carbon atoms, arranged in hexagonal rings. Strong covalent atoms between carbon atoms in rings, forces between layers. Delocalised system of electrons between the layers
- 34FullereneA group of allotropes of carbon, made of balls, 'cages' or tubes of carbon atoms
- 35Carbon nanotubeMolecular-scale tubes of graphite-like carbon
