Answer from: ashley54899

The substance is C) Metalloids.

Explanation:

Metalloids are semiconductors since they are neither great nor poor conductors of electricity as they conduct it only under certain conditions.

Due to presence of free electron in the atomic structures of metals, they are considered as best as well as good conductors of electricity. On the other hand, due to absence of free electron, they cannot conduct electricity thus nonmetals are poor conduits of electricity.

Metalloids have the properties of the two nonmetals and metals. Their electronic structures are moderate between those of metals and nonmetals. Thus, they have the ability to direct electricity only under some conditions.

The scientific method is a series of steps followed by scientific investigators to answer specific questions about the natural world. it involves making observations, formulating a hypothesis, and conducting scientific experiments.the steps of the scientific method are •observation-the first step of the scientific method involves making an observation about something that interests you•question-once you've made your observation, you must formulate a question about what you have observed. •hypothesis-once you've made your observation, you must formulate a question about what you have observed. •experiment-once you've developed a hypothesis, you must design and conduct an experiment that will test it.•results-the results are where you report what happened in the experiment. •conclusion-the final step of the scientific method is developing a conclusion.i hope that this you : )
