A chemist studies the elements in the image. The chemist makes the following observations: - Element X: Lustrous, Malleable - Element Y: Lustrous, Brittle What is the most likely classification of Element X and Element Y?

• Element X and Element Y are both metals.

• Element X and Element Y are both metalloids.

• Element X is a metal, and Element Y is a metalloid.

• Element X is a metalloid, and Element Y is a metal.

3. All the known elements are listed in the periodic table.

A chemist has a sample of an element. The chemist makes the following observations of the element:

• Solid

• Malleable

• Shiny

• High electrical conductivity

• High thermal conductivity

• Gray color

• The element could be Ag because Ag is a metal.

• The element could be Sn because Sn is a metalloid.

• The element could be Ge because Ge is a metalloid.

• The element could be Ar because Ar is a nonmetal.

A chemist is studying the element sulfur (S). She looks at the location of sulfur in the periodic table to determine its physical properties. Which describes sulfur based on its location in the periodic table? Select all correct answers.

• Sulfur is a nonmetal.

• Sulfur is a good conductor of electricity.

• Sulfur does not have luster.

• Sulfur is a poor conductor of electricity.

• Sulfur has a bright luster.

List the three kinds of elements and describe the general area each type is found in the periodic table. Then compare the electrical conductivity of the three kinds of elements.

• Metals, nonmetals, and metalloids; metals are on the left, nonmetals on the right, metalloids in between; metals conduct electricity well, nonmetals do not, metalloids have intermediate conductivity.

• Metals, gases, and liquids; metals are on the right, gases in the middle, liquids on the left; gases conduct electricity well, metals do not, liquids have intermediate conductivity.

• Solids, liquids, and gases; solids are on the left, liquids in the middle, gases on the right; solids conduct electricity well, gases do not, liquids have intermediate conductivity.

• Elements, compounds, and mixtures; elements are on the left, compounds in the middle, mixtures on the right; elements conduct electricity well, compounds do not, mixtures have intermediate conductivity.

3. A circuit in a heater needs a material that is a good conductor of electricity.

A circuit in an electronic device needs a material that does not conduct electricity too well or too poorly.

Identify whether metals, nonmetals, or metalloids should be used in the heater and which should be used in the electronic device. Explain your choices.

• Nonmetals

• Metals

• Metalloids

• Insulators
