A sample of a metalloid is heated. What happens to its ability to conduct an electric current?

1. Metalloids have mostly non-metallic properties but sit between metals and non-metals. 2. One of their distinguishing characteristics is that their conductivity increases as their temperature increases. 3. This is the opposite of what happens in metals. 4. The behaviour is called semi-conductance and the materials are called semi-conductors. 5. Silicon and germanium are the usual examples and they matter in digital electronics. 6. Expecting the conductivity to drop applies the metal rule, which is the trap here. _Source: Siyavula Physical Sciences Grade 10 (Everything Science, CC BY 4.0), Chapter 2: Classification of matter_
