malleability and ductility
B
shininess and ductility
C
conductivity, malleability, and shininess
D

4

In metals, the properties of malleability and ductility are explained by the fact that metallic atoms can

A
conduct electricity by constantly moving electrons.
B
roll past metallic bonds and form new bonds.
C
bounce light off of their sea of electrons.
D
roll over without breaking their bonds.
5

Nickel and gold combine to make white gold. Which best dscribes white gold?

A
alloy of nickel and gold
B
element of nickel and gold
C
pure metal of nickel and gold
D
atom of nickel and gold
6

The electrons in the valence shell of many atoms do not leave the atom because the protons in the nucleus attract the electrons. However, in metals,

electrons can flow from one atom to another.
D
protons can flow from one atom to another.

B
Bernie relied on ductility, Nicholas relied on malleability, and Matt relied on appearance.
C
Bernie relied on malleability, Nicholas relied on appearance, and Matt relied on conductivity.
D
Bernie relied on malleability, Nicholas relied on ductility, and Matt relied on appearance.

The electrons between atoms in metallic bonds

A
allow for bonding metals to be stable.
B
are attracted to the neutrons of the metal.
C
are stationary and provide durability to the metal.
D
allow for bonding metals to be reactive.

Copper is shiny and reflects light, which will cook the food.
B
Copper is malleable and can be manipulated to cook food.
C
Copper is ductile and can be stretched to cook the food.
D
Copper is conductive and will absorb heat to cook the food.
