Which of the following elements is a metalloid?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. Silicon.
Silicon is an example of a metalloid. Metalloids are elements that exhibit properties intermediate between metals and non-metals, making them unique in the periodic table. Silicon, widely used in the electronics industry, has a shiny appearance like metals but is brittle and poor in electrical conductivity compared to metals. Other common metalloids include germanium and arsenic. The distinct characteristics of metalloids make them essential in various applications, particularly in semiconductors, alloys, and chemical compounds, contributing significantly to modern technology.
