Front

What is a semiconductor?

Back

A semiconductor is a substance that can conduct electricity under certain conditions, typically metalloids.

Front

What are common properties of nonmetals?

Back

Nonmetals are poor conductors of electricity and heat, and they are not malleable or ductile.

Front

What is the opposite of metals in the periodic table?

Back

Nonmetals have properties that are opposite those of metals.

Front

Where are metalloids located on the periodic table?

Back

Metalloids are found along the staircase line that divides metals and nonmetals.

Front

Give an example of a nonmetal.

Back

Oxygen (O, #8) is an example of a nonmetal.

Front

What is the characteristic of metals regarding conductivity?

Back

Metals are good conductors of electricity and thermal energy.
