How bonding and structure are related to the properties of substances

Question

A. Strong covalent bonds between atoms.
B. Regular arrangement of atoms in layers.
C. High melting points due to strong bonding.
D. Presence of delocalised electrons.

Answer

The correct option is Regular arrangement of atoms in layers.. This answer is correct because it matches the approved learning objective to explain why pure metals may be too soft for some uses in the subtopic Properties of metals and alloys.

Explanation

The correct option is Regular arrangement of atoms in layers.. Regular arrangement of atoms in layers. is correct because it directly supports the approved learning objective to explain why pure metals may be too soft for some uses. This belongs to the subtopic Properties of metals and alloys within How bonding and structure are related to the properties of substances, 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 Properties of metals and alloys.

Common mistake

Properties of metals and alloys correction for Misunderstanding Metal

Students often believe that pure metals are too soft for all uses because they lack strength This error matters in Properties of metals and alloys because it drifts away from the objective: Explain why pure metals may be too soft for some uses.

Correct it by naming the exact chemistry idea, using precise bonding or structure vocabulary, and linking the answer back to Properties of metals and alloys. For this objective, students should explain why pure metals may be too soft for some uses.
