If you have an unknown material that is a brittle solid and semiconductive, what kind of substance would it be?(1 point) Responses It could be a metal. It could be a metal. It could be a nonmetal or a metalloid. It could be a nonmetal or a metalloid. It must be a nonmetal. It must be a nonmetal. It must be a metalloid.
It could be a nonmetal or a metalloid.
Based on the given information, the substance could be a nonmetal or a metalloid.
To determine the type of substance based on the given characteristics of a brittle solid and semiconductive material, we can use the periodic table as a guide.
1. Start by identifying the key properties mentioned: brittle solid and semiconductive.
2. A brittle solid is a substance that breaks or shatters easily when subjected to stress or force.
3. Semiconductive materials have electrical conductivity between that of conductors (metals) and nonconductors (insulators).
4. Metals generally possess high electrical and thermal conductivity and exhibit ductility (they can be bent or stretched without breaking).
5. Nonmetals, on the other hand, do not exhibit metallic properties and tend to be poor conductors of electricity and heat.
6. Metalloids have properties in between metals and nonmetals, including both metallic and nonmetallic properties.
Based on the information above, a brittle solid that is semiconductive could be either a metalloid or a nonmetal. However, since the material is semiconductive, it is more likely to be a metalloid than a nonmetal, as nonmetals are generally poor conductors of electricity.
So, the most appropriate response would be: It could be a nonmetal or a metalloid.
