Do you know how many different elements there are?

Multiple Choice

what is matter?

• energy and heat

• atoms and energy

• anything that has mass and takes up space.

• everything living

Multiple Choice

What is the smallest particle of matter?

• an atom

• a cell

• a proton

• an electron

Multiple Choice

can atoms be seen with a microscope?

• yes

• no

Multiple Choice

does every single carbon atom have the same physical and chemical properties as all the other carbon atoms?

• yes

• no

Multiple Choice

A student has a sample of an element. Which describes a trait this sample must have to be considered an element?

• It must be a liquid at room temperature.

• it must contain only 1 type of atom.

• it contains different types of particles

Multiple Select

solids (check all that apply)

• have fixed volume

• have fixed shape

• are rigid

• can be squashed or compressed

Multiple Select

liquids (check all that apply)

• have fixed shape

• have fixed volume

• are rigid

• can be squashed

Multiple Select

• have fixed volume

• can be squashed or compressed

• have the most energy

Multiple Choice

What happens to the temperature of a substance at a phase change?

• it lowers

• it remains the same

• it gets higher

Multiple Choice

what happens to atoms when they are heated?

• nothing, they remain the same

• they move slower

• they move faster

• they split apart

Multiple Choice

A metal lid of a jar is hard to open. After being held under warm water it is easier to open. Why is this?

• water increased the pressure under the lid

• the jar shrunk with the warm water

• the lid expanded with warm water

• the water acted as a lubricant

Multiple Choice

Does the melting point of the element Gallium change with the amount of Gallium being investigated?

• yes, less Galium would have a lower melting point

• no, gallium is gallium. it all has the same melting point.

Multiple Choice

Does the density of elemental Copper change with the amount of copper being investigated?

• yes, more copper would be more dense

• no, copper is copper. it all has the same density

Multiple Choice

How many elements have the same physical state, melting point, and boiling point as another element.

• none, all elements are unique in their properties

• 18

• 50

• 100

Multiple Choice

Does the boiling point of the element Bromine change with the size of the Bromine sample?

• Yes, a larger sample would boil at a hotter temperature

• No, all bromine boils at 58.8C

Multiple Choice

Does the malleability of the element Aluminum change with the amount of aluminum being investigated?

• yes

• no

Multiple Choice

• the iron bar magnet has different elements than the horseshoe magnet

• the iron bar magnet has different atoms than the horseshoe magnet

• they're both elemental iron and have the same type of atoms

Multiple Select

In a chemical reaction what happens

• bonds are made or broken

• new substances are made

• products are the same as before the reaction

Multiple Choice
