2.4.1—Bonding continuum 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
