Why are many metalloids useful in electronic components?
They never carry current under any condition.
Their conductivity can lie between conductor and insulator behavior.✓Respuesta correcta
They are perfect conductors in every situation.
They are all liquid at room temperature.
Explicación
Many metalloids behave as semiconductors, allowing their electrical response to fall between consistently good conduction and insulation. Describing them as perfect conductors or as materials that never conduct erases the controllable middle behavior.
