Question

row bond cause physical property of compound 1 ? electron sharing among many atoms ductile 2 ? electron sharing between two atoms brittle 3 ? ? brittle what type of bond is most likely being represented in row 1? ion - dipole ionic metallic covalent

Explanation:

Step1: Recall bond - type characteristics

Metallic bonds involve electron sharing among many atoms.

Step2: Match with physical property

Metallic - bonded compounds are often ductile.

Step3: Analyze other bond types

Ion - dipole bonds involve an ion and a dipole, ionic bonds are due to electron transfer, and covalent bonds (in the common sense here) usually refer to electron sharing between two atoms which is not the case described for row 1.

Answer:

C. metallic
