Bonding Structure and Physical Properties

The ability of a material to conduct heat or electrical energy is called:

• conductivity
• ductility
• malleability
• fusibility

Which type of bonding allows for the conduction of electricity in the solid state?

• Metallic
• Ionic
• Covalent

A mystery substance has a low melting point, does not dissolve in water well, does not conduct electricity, and is made of nonmetals. Which type of substance is it most likely to be?

• Metal
• Ionic
• Covalent

A mystery substance has a high melting point, does not dissolve in water, conducts electricity, and is made of metals. Which type of substance is it most likely to be?

• Metal
• Ionic
• Covalent

A mystery substance has a high melting point, dissolves in water, does not conduct electricity when it is solid, and is made of metals and nonmetals. Which type of substance is it most likely to be?

• Metal
• Ionic
• Covalent

The ability of a material to deform, usually by stretching along its length. This property allows us to make wires.

• conductivity
• ductility
• malleability
• hardness

The ability of a material to be bended and shaped in all directions without cracking or breaking.

• hardness
• ductility
• malleability
• conductivity

Which two substances are ionic compounds?

• sodium chloride (NaCl)

• carbon dioxide (CO₂)

• water (H₂O)

• magnesium oxide (MgO)

Which three of the following are features of ionic compounds? (click 3 boxes)

• They have bonds between metals and non-metals.

• They have bonds between two non-metals.

• They form simple molecular structures.

• They form giant ionic lattices.

• They involve the transfer of electrons.

Ionic compounds form giant ionic lattices. What forces hold the giant ionic lattices together?

• strong frictional forces between the surfaces of the atoms

• strong magnetic forces of attraction between the poles of ions

• strong electrostatic forces of attraction between oppositely charged ions
