Exam points
- Identify the predominant bonding type in a metal, ionic compound or covalent material from its composition and structure.
- Explain how electronegativity and valence-electron behaviour lead to ionic, covalent or metallic bonding.
- Use a material such as magnesium diboride to show why bonding categories are useful but simplified and may overlap.

IB Chemistry SL 2.4.1 Bonding Continuum Questions question 1
[Maximum number: 1]
Iron may be extracted from iron (II) sulfide, FeS.
Iron (II) sulfide, FeS , is ionically bonded.
Suggest why chemists find it convenient to classify bonding into ionic, covalent and metallic.
allows them to explain the properties of different compounds/substances OR enables them to generalise about substances
OR enables them to make predictions
