Question
- A. Electrons that belong to the non-metal atom
- B. Electrons that belong to the metal atom
- C. Shared electrons between two atoms
- D. Electrons that are delocalised
Answer
The correct option is Electrons that belong to the metal atom. This answer is correct because it matches the approved learning objective to interpret dot and cross diagrams that show electron transfer in simple ionic compounds in the subtopic Ionic bonding.
Explanation
The correct option is Electrons that belong to the metal atom. Electrons that belong to the metal atom is correct because it directly supports the approved learning objective to interpret dot and cross diagrams that show electron transfer in simple ionic compounds. This belongs to the subtopic Ionic bonding within Chemical bonds, ionic, covalent and metallic, so the explanation must stay tied to that curriculum context. The other options are incorrect because they either do not answer this learning objective, use a vague statement, or move away from Ionic bonding.
Common mistake
Misinterpreting Dot and Cross Diagrams
Students often confuse the dots and crosses in dot and cross diagrams, thinking they represent different types of atoms rather than the electrons from the same atom.
Remind students that the dots and crosses represent the same atom's electrons and that they should focus on how the electrons are transferred between the metal and non-metal atoms.
