Metals Nonmetals Metalloids

A student is given a sample of an unknown substance. He is asked to determine if it is classified as a metal, a metalloid, or a nonmetal. He discovered that the unknown element conducted some heat and electricity, had a shiny luster, and broke easily. This element is most likely a 

• metal
• nonmetal
• metalloid
• cannot be determined

Which table below correctly lists the properties of metals and nonmetals? *

• A
• B
• C
• D

Which of the following is a property of a non-metal?

• Conducts electricity and heats well
• Can be hammered into thin sheets
• Is brittle and breaks easily
• Has a shiny, metallic luster

All of the following are properties used to classify elements as metals, non-metals, and metalloids EXCEPT —

• texture
