Correct option is D
The correct answer is (D) Semiconductor
Explanation:
Metalloids are elements that have properties intermediate between metals and non-metals.
Semi conductivity is one of the defining properties of metalloids, meaning they can conduct electricity under certain conditions, making them essential in the manufacture of electronic devices.
Silicon and germanium are common examples of metalloids used in semiconductors.
Information Booster:
- Metalloids are also called semimetals.
- They have a shiny appearance like metals but are brittle like non-metals.
- Their electrical conductivity increases with temperature, which is a key feature of semiconductors.
Additional Knowledge :
- Malleable : This is a property of metals, meaning they can be hammered into thin sheets.
- Ductile : Ductility is also a property of metals, referring to the ability to be drawn into wires.
- Sonorous : Metals are sonorous, meaning they produce a sound when struck, but this is not a property of metalloids.
