Properties of Period 3 elements and their oxides (A-level only)
Question
- A. Ionic bonding
- B. Covalent bonding
- C. Metallic bonding
- D. Hydrogen bonding
Answer
Ionic bonding
Explanation
The correct option is Ionic bonding. Ionic bonding is the best answer because it directly supports the AQA A-Level Chemistry objective to explain melting point trends of Period 3 oxides. This reasoning is anchored to Period 3 oxides (A-level only) in Properties of Period 3 elements and their oxides (A-level only), and it separates Period 3 oxide from similar A-Level ideas rather than relying on a vague recall statement. Other options are weaker if they use the wrong evidence, calculation, mechanism, observation, unit, or conclusion for this subtopic.
Common mistake
Misunderstanding Bonding Types
Students often confuse the types of bonding in Period 3 oxides, thinking that all oxides have ionic bonding.
Remember that Period 3 oxides can have different types of bonding. For example, SiO2 has covalent bonding, while Na2O has ionic bonding. Review the specific bonding characteristics of each oxide. Keep the correction anchored to Period 3 oxides (A-level only) and the objective: Explain melting point trends of Period 3 oxides.
