No metales

Nonmetals typically have four or more electrons in their outer shell, which gives them distinct physicochemical properties compared to metals. They are generally poor conductors of heat and electricity. Examples of classical nonmetals include sulfur, oxygen, carbon, and nitrogen.

What is a common characteristic of nonmetals in terms of their electron configuration?

• They have no electrons in their outer shell.

• They have four or more electrons in their outer shell.

• They have two electrons in their outer shell.

• They have one electron in their outer shell.

How do nonmetals generally compare to metals in terms of conductivity?

• Nonmetals conduct electricity but not heat.

• Nonmetals conduct heat but not electricity.

• Nonmetals are excellent conductors of heat and electricity.

• Nonmetals are poor conductors of heat and electricity.

Which of the following is NOT a classical nonmetal?

• Sulfur

• Oxygen

• Iron

• Carbon

Which element is a classical nonmetal?

• Gold

• Nitrogen

• Copper

• Silver

What property is shared by sulfur, oxygen, carbon, and nitrogen?

• They are all metals.

• They are all good conductors of electricity.

• They all have two electrons in their outer shell.

• They are all classical nonmetals.
