The correct formula for a compound formed from the elements Al and O is
Al302
ΑΙΟ.
Al203
Al20.
Al03.
The Correct Answer and Explanation is :
The correct formula for the compound formed from the elements Aluminum (Al) and Oxygen (O) is Al₂O₃.
Explanation:
The formation of compounds from elements follows specific rules based on the charges of the ions they form. Let’s break down the reasoning:
- Aluminum (Al):
- Aluminum is a metal that typically forms a cation with a charge of +3 (Al³⁺) because it loses three electrons in order to achieve a stable electron configuration, similar to the nearest noble gas (Neon).
- Oxygen (O):
- Oxygen is a non-metal that typically forms an anion with a charge of -2 (O²⁻) by gaining two electrons to complete its outer electron shell, achieving a stable configuration similar to neon.
- Balancing the Charges:
- To form a neutral compound, the total positive charge must equal the total negative charge. Since Aluminum has a +3 charge and Oxygen has a -2 charge, we need to find the smallest multiple of 3 and 2 that results in equal total charges.
- Two Aluminum ions (Al³⁺) will contribute a total positive charge of +6.
- Three Oxygen ions (O²⁻) will contribute a total negative charge of -6.
- Therefore, the formula for the compound is Al₂O₃ because it results in a neutral charge: 2(Al³⁺) + 3(O²⁻) = 0.
Final Compound:
- The compound formed is called Aluminum Oxide, and its chemical formula is Al₂O₃. This compound is a white, odorless powder, commonly found in materials like ceramics and used in industrial processes, such as the production of aluminum metal.
