B. ionic
C. metallic
D. covalent



Answer :

To determine the type of bond represented in row 1, we can analyze the provided information.

Row 1 of the table provides the following clues:
- Cause: Electron sharing among many atoms
- Physical property of compound: Ductile

Let's interpret these clues one step at a time:

1. Electron sharing among many atoms:
- This is a distinguishing characteristic of a certain type of bond where electrons are delocalized across a lattice of atoms. This delocalization allows the electrons to move freely throughout the structure.

2. Ductile:
- The property of being ductile indicates that the material can be stretched into thin wires without breaking. This property is typically associated with the ability of atoms to slide past one another without breaking the bond, which requires a sea of delocalized electrons.

Given these characteristics, there is one type of bond that fits both the electron sharing among many atoms and the ductile nature of the material:

- Metallic bonds:
- In metallic bonding, electrons are not bound to any specific atom but are instead shared among many atoms, forming a "sea of electrons". This electron mobility allows metals to be ductile and enables them to conduct electricity.

Therefore, the bond type most likely represented in row 1 is metallic.

This analysis aligns precisely with the following conclusion:

The type of bond represented in row 1 is metallic (3).
