Naomi is testing the different properties of an unknown solid. Her results are located in the chart. Which statement describes the chemical nature of the bonding in the substance?

Question illustration
A
When chilled, the atoms rolled over each other while still staying together, causing a lower temperature.
B
When heated, the valance electrons increased their speed and transferred the heat from electron to electron.
C
When treated with light, the atoms rolled over each other while still staying together, causing a reflection of light.
D
When treated with an applied force, the valence electrons increased their speed and transferred the change from electron to electron.

Anjuli is looking at four different metal samples on the counter. Three are solid, and one is a liquid. Which statement about the liquid metal is most likely true?

A
The liquid metal is gold.
B
The liquid metal is mercury.
C
The liquid metal was superheated.
D
The liquid metal was supercooled.

Jasmine is a cook, and she wants to buy new equipment. She is presented with dishes made of copper, clay, plastic, and glass. She selects the copper pot because she does most of her cooking on the stove.Which explains why she most likely chose copper?

A
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.
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,

A
electrons can flow from one atom to another.
B
protons can flow from one atom to another.
C
protons attract protons of other atoms.
D
electrons attract electrons of other atoms.
7

The electrons between atoms in metallic bonds

A
allow for bonding metals to be reactive.
B
allow for bonding metals to be stable.
C
are stationary and provide durability to the metal.
D
are attracted to the neutrons of the metal.
8

Metallic bonds are important to how paperclips are both made and used.

Question illustration
A
Conduction is important for making paperclips, and shininess is important for using them.
B
Shininess is important for making paperclips, and ductility is important for using them.
C
Ductility is important for making paperclips, and malleability is important for using them.
D
Malleability is important for making paperclips, and conduction is important for using them.
9
