Front

What are metals?

Back

Metals are elements that are good conductors of heat and electricity, have a shiny appearance, and can be bent or shaped easily.

Front

What are nonmetals?

Back

Nonmetals are elements that are poor conductors of heat and electricity, often have a dull appearance, and are brittle in solid form.

Front

What are metalloids?

Back

Metalloids are elements that have properties of both metals and nonmetals, making them semiconductors of electricity.

What is conductivity?

Back

Conductivity is the ability of a material to conduct heat or electricity.

Front

Why are metals used in electrical wires?

Back

Metals are used in electrical wires because they are good conductors of electricity.

Front

What is the periodic table?

Back

The periodic table is a chart that organizes all known elements based on their atomic number, electron configuration, and recurring chemical properties.

Front

What is a characteristic property of metalloids?

Back

Metalloids can conduct electricity better than nonmetals but not as well as metals.
