Amphoteric oxides are oxides that can act as both acids and bases. They react with acids to form salts and water, and with bases to form salts and water, showing both acidic and basic properties.

1. Element 13 is Aluminum (Al). Aluminum Oxide (Al2O3) is amphoteric. It reacts with acids to form a salt and water and with bases to form aluminates.

2. Element 14 is Silicon (Si). Silicon Oxide, also known as Silica (SiO2), is generally considered acidic but can behave as amphoteric under certain conditions.

3. Element 15 is Phosphorus (P). Phosphorus has several oxides, the most common of which are P4O6 and P4O10. Both of these oxides are acidic, not amphoteric.

4. Element 16 is Sulfur (S). Sulfur has several oxides, the most common of which are SO2 and SO3. Both of these oxides are acidic, not amphoteric.

So, among the elements 13, 14, 15, and 16, only Aluminum and Silicon form amphoteric oxides under certain conditions.
