What is a metal?
An element that is typically a gas or brittle solid
An element that is typically solid, shiny, malleable, and a good conductor of heat and electricity
An element that has properties of both metals and nonmetals
A pure substance composed of different types of atoms
Which of the following describes a nonmetal?
Shiny and malleable
Good conductor of heat and electricity
Typically not shiny, not malleable, and poor conductors of heat and electricity
Always a liquid at room temperature
A group of students were discussing their lab results after A group of students were discussing their lab results afterconducting an investigation on metals, nonmetals, metalloids, and rare earth elements. This is what they said:
Zane: “Rare earth elements are not metallic and used in many different technologies.”
Shae: “Carbon is an example of a nonmetal because it is dull and a poor conductor.”
Amy: “Nonmetals are malleable." Who was correct?
Zane
Shae
Amy
Two students tested the physical properties of an unknown element. The chart below lists their findings.Based on the chart, which of the following is true?
The students need to conduct additional investigations to determine more physical properties before the unknown element can be classified.
The students tested a metal because the physical properties describe metals.
The students tested a metalloid because the physical properties are of both a metal and nonmetal.
The students tested a nonmetal because the physical properties describe nonmetals
The table shows the classification and physical state of four elements. Which element most likely has a shiny luster?
Carbon
Hydrogen
Arsenic
Cobalt
Elements that have properties of both metals and nonmetals; sometimes referred to as semiconductors.
Metals
Nonmetals
Metalloids
Rare earth elements.
Elizabeth is making a circuit for class. She is trying to decide what type of material to use to make the wires so they can conduct electricity most efficiently. What type of material should the wires be made out of so that they best conduct electricity?
Ceramic
Metal
Nonmetal
Metalloid
The Periodic Table can be broken into three different sections. In which section would you expect to find an element that is a gray, shiny, and malleable?
An element that is a gray, shiny, and malleable, is a metalloid; therefore, it can be found in Section 2.
An element that is a gray, shiny, and malleable, is a nonmetal; therefore, it can be found in Section 3.
An element that is a gray, shiny, and malleable, is a metal; therefore, it can be found in Section 1.
An element that is a gray, shiny, and malleable, is a rare earth element; therefore, it can be found in Section 2.
What is a rare earth element?
A. A type of rock found in the Earth's crust
B. One of 17 elements on the periodic table, including lanthanides, scandium, and yttrium
C. A common metal like copper or tin
D. A type of fossil fuel
