Below are sample questions representative of the exercises included on this worksheet and related 9.28 Metals, Nonmetals, and Metalloids skill assessments:

Problem 1Difficulty: Mastery

Use the accompanying evidence table for Unknowns U and V. Which classification pair is best?

AU = nonmetal; V = metal

BU = metal; V = nonmetal

CU = metalloid; V = metal

DU = nonmetal; V = metalloid

Solution & Explanation:Unknown U has upper-right location, brittleness, dullness, and poor conductivity, which fit a nonmetal. Unknown V lies on the stair-step and is a shiny brittle semiconductor, which fits a metalloid.

Problem 2Difficulty: Mastery

A solid element is in the upper-right region, crumbles when pressed, and is a poor conductor. What should you classify it as?

AMetal, because any solid element is metallic

BNonmetal, because upper-right location, brittleness, and poor conductivity agree

CMetalloid, because crumbling is the only clue needed

DAlkali metal, because poor conductivity means it is in Group 1

Solution & Explanation:All three clues support nonmetal classification. The sample is solid, but that alone does not make it a metal.

Problem 3Difficulty: Mastery

Which statement best explains why metalloids are important in electronics?

AThey never conduct electricity under any conditions

BThey are always better conductors than copper

CTheir intermediate conductivity can be useful because it can be controlled

DThey are all noble gases stored in bulbs

Solution & Explanation:Metalloids are often semiconductors, so their conductivity can be controlled for electronic uses.
