Answer 3

Metals are good conductors of heat and electricity, and are malleable (they can be hammered into sheets) and ductile (they can be drawn into wire).
Nonmetals: Nonmetals are generally dull or non-reflective and do not have a metallic luster or conduct electricity and heat.
Metalloids: Metalloids can have a metallic or nonmetallic appearance, they conduct heat and electricity but not as well as metals and are used for semi conductor computer chips.
