Conductivity is a physical property of matter that describes its ability to
reflect light from its lustrous surface
transfer thermal and electrical energy
exist in nature as a solid, liquid, or gas
be hammered and rolled into thin sheets
Iron (Fe) is classified as a metal while Silicon (Si) is classified as a metalloid. Which physical property do these two elements most likely have in common? They both
exist as gases at room temperature
have a metallic shine or luster
are brittle and shatter easily
conduct electricity very well
Which of the following would help a student classify an unknown element as a metal, metalloid, or non-metal?
measure its conductivity
determine its density
find its melting point
observe its color
Unlike non-metals, most metals tend to
have less luster and shine
break easily when hammered
be gases at room temperature
conduct heat and electricity well
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
A student tested the conductivity of four elements using an incomplete electrical circuit. When the element is placed in the circuit, the bulb lights up brightly, lights up dimly, or does not light up at all based on the element’s ability to conduct electricity.

Hydrogen
Arsenic
Krypton
Copper
