Answer

2. Two metalloids commonly used in electronics are silicon (Si) and germanium (Ge). ### 3. Metalloids are important in making semiconductors because their intermediate electrical conductivity can be easily modified through doping, allowing precise control over the flow of electricity in electronic components. Explanation 1. Identifying Common Metalloids in Electronics The most commonly used metalloids in electronics are silicon (Si) and germanium (Ge). Both elements have properties between metals and nonmetals, making them ideal for electronic applications. 2. Importance of Metalloids in Semiconductors Metalloids like silicon and germanium have electrical conductivity between that of conductors and insulators. This intermediate conductivity allows their electrical properties to be precisely controlled by adding impurities (a process called doping), which is essential for creating semiconductors used in devices such as diodes, transistors, and integrated circuits.
