metalloids are useful as semiconductors in modern electronics, like smartphones. which feature of a smartphone is made possible by metalloids?\ntouchscreen\nability to vibrate\nsmall size\nlong battery life
Answer
Brief Explanations:
Metalloids as semiconductors are crucial for the functionality of electronic - circuit components. The touchscreen of a smartphone works due to the electrical conductivity and semiconductor properties of materials (which can involve metalloids). The ability to vibrate is due to a vibrating motor, small size is related to miniaturization of components in general, and long battery life is related to battery - chemistry and power - management systems, none of which are directly related to the semiconductor property of metalloids.
Answer:
A. touchscreen
