Question Answer
Physical property Any property that is measurable, whose value describes a physical state or appearance
Chemical property A characteristic of a substance that is observed during a chemical reaction
Strong material One that cannot be easily broken
Brittle material One that can be easily broken
Malleable Can be bent, hammered or squashed into different shapes
Ductile Can be stretched out into wires
Lustrous The word used to describe the shiny appearance of metals when polished
Lattice A structure consisting of a regular three dimensional pattern
Structure of a metal Lattice of positive ions, through which a 'sea' of electrons are free to move
Metallic bonds The electrostatic attraction between positive metal ions and negative delocalised electrons
Ionic compounds Compounds where the particles are joined by ionic bonds
Ionic bonds Bonds formed between oppositely charged particles
Ion A charged atom or group of atoms
Octet rule Atoms 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
Oxide \(O^{2-}\)
Hydroxide \(OH^{-}\)
Nitrate \(NO_3^{-}\)
Chloride \(Cl^{-}\)
Bromide \(Br^{-}\)
Iodide \(I^{-}\)
Sulfate \(SO_4^{2-}\)
Carbonate \(CO_3^{2-}\)
Phosphate \(PO_4^{3-}\)
Unit cell The simplest way of drawing the arrangement of ions in the lattice
Bonds Forces of attraction that hold atoms together
Cation A positively charged ion
Anion A negatively charged ion
Electrostatic forces Forces of attraction between positively and negatively charged objects
Covalent bonds Involve the sharing of electrons between two or more atoms
Molecule The structure that results when two or more atoms are joined together by a covalent bond Eg: Water
Allotropes Different physical forms of the same substance Eg. Diamond and graphite are contain covalent bonds between carbon atoms
Bonding in diamond Carbon 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
Bonding in graphite Layers 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
Fullerene A group of allotropes of carbon, made of balls, 'cages' or tubes of carbon atoms
Carbon nanotube Molecular-scale tubes of graphite-like carbon
