I'm confused by what element(s) can be identified to have these properties.
The following is text from my 2019-2020 Kaplan MCAT General Chemistry book under the metalloids section
Silicon (Si) has a metallic luster but is brittle and a poor conductor
So onto the MCAT Concept Check 2.2:
Identify a few elements that likely possess the following properties
- Good conductivity but brittle
I flip to the answer key and it says:
Metalloids exhibit brittleness but good conductivity
So I'm confused how this makes sense because Si was the main example they provided in that passage, and it seems to contrast the two points they make.
So what is an actual example of good conductivity but brittle??
