Metals, Non-Metals, and Metalloids

Their Properties by Michael Potthoff

Metals

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.

Non-Metals

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.

Metalloids

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.
