Dispersion – the act or manner of spreading something. ( root word- Dis- = apart. Examples; disappear, disgrace, disappoint).

Indicator – that which gives an indication, an idea of the relative value or quality of something.

Ionic compounds – compounds consisting of ionic bonds where the attraction of oppositely charged ions forms the bond. In fact, a pure ‘ionic compound’ is not possible: some covalent bonding is always present. A bond is  termed ‘ionic’ when the electrical attraction is greater than the covalent attraction. High melting and boiling points are characteristic of ionic compounds.

Isomers – compounds that have the same molecular formula but differ in their arrangement and properties.

Kinetic – motion or movement. Kinetic energy is the energy of a molecule in movement (see potential energy).

Polarity – having two oppositely charged poles.

Properties – the characteristic qualities of a something.

Proportion (noun),  Proportional (adjective) – the relative size or quantity of the parts.

Sufficient – having or being enough.                              

Van der Waals – a Dutch physicist who won the 1910 Nobel Prize for his work on the behaviour of gases. His name was given to certain weak electrostatic bonds between atoms and molecules.

Velocity – the rate of speed or movement.

Volatile (adjective), Volatility (noun) – describes a substance that evaporates at normal temperatures.
