Science Unit 2 Review

What are some properties of metals?

• High electrical and thermal conductivity, malleability, ductility, and shiny appearance.

• High electrical and thermal conductivity, brittleness, and dull appearance.

• Low electrical and thermal conductivity, malleability, and shiny appearance.

• Low electrical and thermal conductivity, brittleness, and dull appearance.

What are some properties of nonmetals?

• Nonmetals have low melting and boiling points, are poor conductors of heat and electricity, and tend to gain electrons in chemical reactions.

• Nonmetals have high melting and boiling points, are good conductors of heat and electricity, and tend to gain electrons in chemical reactions.

• Nonmetals have high melting and boiling points, are good conductors of heat and electricity, and tend to lose electrons in chemical reactions.

• Nonmetals have low melting and boiling points, are good conductors of heat and electricity, and tend to lose electrons in chemical reactions.

What are some properties of metalloids?
