Metals, Nonmetals, & Metalloids

What is a common property of metals?

• Metals are good conductors of heat and electricity.

• Metals are poor insulators of sound.

• Metals are typically brittle and break easily.

• Metals are usually transparent to light.

Where are metalloids located on the periodic table?

• In the far left column of the periodic table.

• Along the stair-step line on the periodic table.

• In the bottom row of the periodic table.

• In the top right corner of the periodic table.

Give an example of a metalloid.

• Silicon (Si)

• Iron (Fe)

• Copper (Cu)

• Aluminum (Al)

What is a nonmetal?

• An element that typically lacks the properties of metals, such as conductivity and luster.

• An element that is a good conductor of electricity and heat.

• An element that has a shiny appearance and is malleable.

• An element that can easily lose electrons to form positive ions.

What is the role of metalloids in technology?

• They are used in the production of semiconductors and electronic devices.

• They are primarily used as insulators in electrical applications.

• They serve as catalysts in chemical reactions.

• They are used to enhance the strength of metals.

What is the general state of nonmetals at room temperature?

• Nonmetals are always gases at room temperature.

• Nonmetals can be gases (like oxygen), liquids (like bromine), or solids (like sulfur) at room temperature.

• Nonmetals are always solids at room temperature.

• Nonmetals are only found in liquid form at room temperature.

What are the three main categories of elements in the periodic table?

• Metals, Nonmetals, and Metalloids.

• Noble gases, Alkali metals, and Transition metals.

• Halogens, Lanthanides, and Actinides.

• Metalloids, Nonmetals, and Rare earth elements.

What is the significance of the stair-step line on the periodic table?

• It separates metals from nonmetals and indicates the location of metalloids.

• It shows the atomic mass of elements.

• It indicates the reactivity of elements.

• It represents the number of protons in an atom.

What is the typical appearance of metals?

• Metals usually have a dull appearance and are brittle.

• Metals usually have a shiny appearance and are malleable.

• Metals usually have a rough texture and are non-malleable.

• Metals usually have a transparent appearance and are fragile.

What is a metalloid?

• An element that has properties of both metals and nonmetals.

• An element that is a good conductor of electricity.

• An element that is a poor conductor of heat.

• An element that is always a gas at room temperature.
