Question

the incomplete table below shows selected properties of compounds that have ionic, covalent, or metallic bonds.

row	substance	type of bond	likely property
2	?	covalent	does not conduct electricity
3	?	?	malleable

which substance would be most suitable for row 3?

• sodium chloride (nacl)
• silver (ag)
• nitrogen (n₂)
• propane (c₃h₈)

Explanation:

Step1: Recall bond - property relationships

Metallic bonds result in malleability. Ionic compounds like sodium chloride (NaCl) are brittle. Covalent compounds like nitrogen ($N_2$) and propane ($C_3H_8$) do not conduct electricity well and are not malleable in the same sense as metals. Silver (Ag) has metallic bonds and is malleable.

Answer:

B. silver (Ag)
