Out of the group 14 elements, C and Ge do not react with water and lead is also unaffected because of the protective oxide film formation.
Sn reacts with steam to form SnO2 and H2.
Sn+2H2O⟶SnO2+2H2

Decomposition of steam by Group 14 element Sn:
- Group 14 elements:
- Group 14 elements include carbon (C), silicon (Si), germanium (Ge), tin (Sn), and lead (Pb).
- Decomposition of steam:
- When steam (H2O) is decomposed, it forms dioxide (O2) and liberates hydrogen gas (H2).
- Reaction with Sn:
- Sn (tin) belongs to Group 14 elements and has the capability to decompose steam.
- The reaction of Sn with steam can be represented as:
- Sn(s) + 2H2O(g) → SnO2(s) + 2H2(g)
- In this reaction, tin reacts with steam to form tin dioxide and liberate hydrogen gas.
- Explanation:
- Among the given Group 14 elements, only tin (Sn) has the ability to decompose steam to form dioxide and liberate hydrogen gas.
- Pb (lead), Cd (cadmium), and Ge (germanium) do not exhibit this behavior.
Therefore, the correct answer is option 'A', which is Sn (tin).
