Question
An element L consists of molecules.
- Which type of bond is present in the particles that make up L?
- When L is heated with iron metal, it forms a compound FeL. What chemical term would you use to describe change undergone by L?

Solution
- Covalent bonding is present in L as the bond is formed between the same atoms.
- On heating, Fe undergoes oxidation and loses two electrons as follows:
\[\ce{Fe - 2^{e^-} -> Fe^{2+}}\]
L takes up two electrons and undergoes reduction.
