Which amongst the following element can from amphoteric oxide ?

Options

A. Mg
B. N
C. Al
D. C

Answer

To determine which element can form an amphoteric oxide, we need to understand what amphoteric oxides are and identify the relevant elements from the options provided.

### Step-by-Step Solution:

1. **Definition of Amphoteric Oxides**:
Amphoteric oxides are oxides that can react with both acids and bases. This means they can exhibit both acidic and basic properties.

2. **Examples of Amphoteric Oxides**:
Common examples of amphoteric oxides include:
- Zinc oxide (ZnO)
- Aluminum oxide (Al2O3)
- Beryllium oxide (BeO)
- Lead(II) oxide (PbO)
- Tin(II) oxide (SnO)
- Germanium oxide (GeO)

3. **Identifying Elements**:
From the options given (not specified in the question), we need to identify which of these elements can form amphoteric oxides.

4. **Using the Mnemonic**:
A mnemonic to remember some common amphoteric oxides is:
"Zanabe Ali Ne Bikar Gaya Punjabi Song Aaj Sab Bekari Indore Gaye"
- ZN = Zinc (ZnO)
- AL = Aluminum (Al2O3)
- BE = Beryllium (BeO)
- GA = Gallium (Ga2O3)
- SN = Tin (SnO)
- PB = Lead (PbO)
- BI = Bismuth (Bi2O3)
- IN = Indium (In2O3)
- GE = Germanium (GeO)

5. **Conclusion**:
Based on the mnemonic and the knowledge of amphoteric oxides, we can conclude that elements like Aluminum (Al), Zinc (Zn), and others listed above can form amphoteric oxides.

6. **Final Answer**:
If Aluminum (Al) is one of the options, it is the correct answer as it forms Al2O3, which is an amphoteric oxide.
