Metals, Non-Metals, and Metalloids

Their Properties by Michael Potthoff


1. Good Conductors: metals are excellent conductors of heat and electricity.

2. High Density: metals have lots of mass in relation to volume.

3. Malleable: most metals can be hammered into sheets.


1. Poor Conductors: non-metals are poor conductors of heat and electricity.

2. Not Malleable: brittle breaks easily.

3. No Luster: very dull appearance, not shiny.


1. Metalloids are solids.

2. Metalloids conduct heat and electricity better than nonmetals but not as well as metals.

3. Metalloids are ductile and malleable.
