The correct Answer is:
To determine which element forms only one hydride among the elements of Group 14 (Carbon family), we can analyze each element's ability to form hydrides. ### Step-by-Step Solution: 1. **Identify the Elements in Group 14**: The elements in Group 14 of the periodic table are Carbon (C), Silicon (Si), Germanium (Ge), Tin (Sn), and Lead (Pb). 2. **Examine Carbon (C)**: - Carbon can form multiple hydrides such as methane (CH₄), ethyne (C₂H₂), and many others. - Therefore, carbon does not fit the criteria of forming only one hydride. 3. **Examine Silicon (Si)**: - Silicon can form various hydrides, including silane (SiH₄) and others based on different structures. - Thus, silicon also does not meet the requirement. 4. **Examine Germanium (Ge)**: - Germanium can form multiple hydrides, similar to silicon, including germane (GeH₄). - Therefore, germanium does not fit the criteria either. 5. **Examine Tin (Sn)**: - Tin can form several hydrides, such as stannane (SnH₄). - Thus, tin does not meet the requirement. 6. **Examine Lead (Pb)**: - Lead forms only one significant hydride, which is lead tetrahydride (PbH₄). - This hydride is known to be unstable and acts as a strong reducing agent. 7. **Conclusion**: - Among the elements analyzed, only Lead (Pb) forms a single hydride, PbH₄. - Therefore, the answer to the question is Lead (Pb). ### Final Answer: The element which forms only one hydride is Lead (Pb). ---
