Barrier Methods: Rusting may be prevented by stopping the water and oxygen getting to the iron with a barrier of grease, oil, paint or plastic.

Galvanising: (coating in zinc) also prevents water and oxygen getting to the iron, but with galvanising even if the barrier is broken the more reactive zinc corrodes before the less reactive iron. During the process, the zinc loses electrons to form zinc ions.

The molecular formula shows the actual number of atoms of each element in a molecule.

The general formula shows the relationship between the number of atoms of one element to another within a molecule. Members of a homologous series share the same general formula. The general formula for alkanes is C_nH_2n+2 and the general formula for alkenes is C_nH_2n.

A structural formula shows how the atoms in a molecule are joined together.

The displayed formula is a full structural formula which shows all the bonds in a molecule as individual lines.

The terms above are demonstrated with the example of butane.

Displayed formula:
Molecular formula: C₄H₁₀
General formula (alkanes): C_nH_2n+2
Structural formula: CH₃ – CH₂ – CH₂ – CH₃

The terms above are demonstrated with the example of ethene, which contains a double bond.

Displayed formula:
Molecular formula: C₂H₄
General formula (alkenes): C_nH_2n
Structural formula: CH₂ = CH₂
