Worksheets6.6C - Metals, Nonmetals, Metalloids Review
Total questions: 10
Worksheet time: 20mins
Two students tested the physical properties of an unknown element. Based on the chart, which of the following is true?
The students tested a metalloid because the physical properties are of both a metal and nonmetal.
The students tested a metal because the physical properties describe metals.
The students tested a nonmetal because the physical properties describe nonmetals.
The students need to conduct additional investigations to determine more physical properties before the unknown element can be classified.
The Periodic Table can be broken into three different sections. In which section would you expect to find an element that is a semiconductor, shiny, and brittle?
An element that is a semiconductor, shiny, and brittle would be a metal; therefore, it can be found in Section 1.
An element that is a semiconductor, shiny, and brittle would be a metal; therefore, it can be found in Section 3.
An element that is a semiconductor, shiny, and brittle would be a metalloid; therefore, it can be found in Section 2.
An element that is a semiconductor, shiny, and brittle would be a metalloid; therefore, it can be found in Section 3.
A group of students were discussing their lab results after conducting an investigation on metals, nonmetals, metalloids, and rare earth elements. This is what they said: Zeke: “Rare earth elements are metallic and used in many different technologies.” Shondra: “Carbon is an example of a metal because it is dull and a poor conductor.” Alyssa: “Malleability describes the ability to be pounded into thin sheets with a hammer. Nonmetals are malleable.” Diego: “Potassium is a nonmetal because it is shiny and ductile.” Based on their discussion, who is correct?
A. Zeke
B. Shondra
C. Alyssa
D. Diego
Plutonium is silver, metallic, soft and ductile when mixed with other metals, never found in large amounts, and found mixed with other elements. It has been used in creating atomic bombs. Based on these properties, plutonium would be classified as a–
Nonmetal
Metalloid
Metal
Rare earth element
