All of these properties describe metals except...

• malleable
• conductors
• brittle 
• shiny

Which element is a metalloid?

• Titanium
• Selenium

• metal
• nonnmetal
• metalloid
• metallica

Aluminum can be hammered into different shapes or rolled into flat sheets. This means Aluminum is 

• ductile
• malleable

• high density

This type of element loses its valence electrons easily.

• metal

• nonmetal

• metalloid

Metals can be drawn into thin wires. This property is known as being

• malleable

• ductile

• conductive

• lusterous

Electrical wires are made from metals such as copper and chromium because --

• wires can be stretched and bent.

• most metals have a metallic luster.

• electricity flows in a complete circuit.

• metals are good conductors of electricity.
