Metals, Nonmetals, Metalloids

Front

What is a metalloid?

Back

A metalloid is an element that has properties intermediate between metals and nonmetals. They are typically semiconductors of electricity.

Front

List two characteristics of metals.

Back

Metals are malleable (can be shaped) and ductile (can be drawn into wires).

Front

What does it mean if a material is ductile?

Back

A ductile material can be easily drawn into wires without breaking.

Front

What is a nonmetal?

Back

A nonmetal is an element that lacks the characteristics of metals, typically poor conductors of heat and electricity.

Front

Which type of element is a good conductor of heat?

Back

Metals are good conductors of heat.

Front

What are some common properties of nonmetals?

Back

Nonmetals are usually brittle in solid form, not malleable or ductile, and poor conductors of heat and electricity.

Front

Name a common metalloid and its use.

Back

Silicon is a common metalloid used in electronics and computer chips.

Front

How do metals generally react with acids?

Back

Metals typically react with acids to produce hydrogen gas and a salt.

Front

What is the difference between a metal and a nonmetal in terms of conductivity?

Back

Metals are good conductors of electricity and heat, while nonmetals are poor conductors.

Front

What is the significance of ductility in metals?

Back

Ductility allows metals to be stretched into wires, which is important for electrical wiring and other applications.
