The most basic oxide of elements group 14 of the periodic table is:

Options

A. `SiO_(2)`
B. `GeO_2`
C. `SnO_(2)`
D. `PbO`

Answer

To determine the most basic oxide of the elements in Group 14 of the periodic table, we need to analyze the basic nature of the oxides formed by these elements: SiO2, GeO2, SnO2, and PbO.

### Step-by-Step Solution:

1. **Identify Group 14 Elements**:
- The elements in Group 14 are Carbon (C), Silicon (Si), Germanium (Ge), Tin (Sn), and Lead (Pb).

2. **List the Oxides**:
- The oxides corresponding to these elements are:
- Carbon: CO2
- Silicon: SiO2
- Germanium: GeO2
- Tin: SnO2
- Lead: PbO

3. **Understand Basicity of Oxides**:
- Basicity refers to the ability of an oxide to react with acids to form salts and water. Basic oxides tend to be formed by metals, while acidic oxides are typically formed by non-metals.

4. **Trend in Basicity**:
- As we move down the group from Carbon to Lead, the metallic character of the elements increases. This increase in metallic character generally correlates with an increase in basicity of their oxides.

5. **Compare the Oxides**:
- SiO2 and GeO2 are more acidic in nature due to the non-metallic character of Silicon and Germanium.
- SnO2 and PbO are more basic because Tin and Lead are more metallic compared to Silicon and Germanium.
- Among these, PbO (Lead oxide) is the most basic because Lead is the heaviest and most metallic element in Group 14.

6. **Conclusion**:
- Therefore, the most basic oxide of the elements in Group 14 is PbO.

### Final Answer:
The most basic oxide of elements in Group 14 of the periodic table is **PbO** (Lead oxide).
