Metalloids are a group of chemical elements that have properties intermediate between those of metals and nonmetals. They are typically semiconductors, meaning they can conduct electricity under certain conditions but not others. This unique characteristic makes them vital in various technological applications.
Observe the image below showing the metalloids on the periodic table.
1. Which of the following is a characteristic property of metalloids?
High electrical conductivity at all temperatures
Poor conductors of heat and electricity
Semiconductors
Always shiny and malleable
2. Which element is an example of a metalloid?
Iron (Fe)
Oxygen (O)
Silicon (Si)
Sodium (Na)
3. Metalloids are found along the line on the periodic table.
4. The ability of a metalloid to conduct electricity can be controlled, making them useful in .
5. All metalloids are shiny and conduct heat well.
True
False
6. Metalloids typically have properties that are a blend of both metals and nonmetals.
True
False
7. Explain why metalloids are considered important in the electronics industry.
8. Name two common metalloids and describe one use for each.
