Question

Which important change in electronic devices, such as televisions and computers, is a result of the use of metalloids as semiconductors?

Electronic devices have become smaller.
Electronic devices are now more brittle.
Electronic devices now use more energy.

Answer 1

Electronic devices have become smaller.

Reason: metalloids like silicon (semiconductors) made possible transistors and integrated circuits, replacing bulky vacuum tubes and allowing miniaturization, higher performance and lower power use — not increased brittleness or energy use.
