Which of the following is most likely a solid that is not a good conductor of electricity? A. Nickel B. Sodium C. Silicon D. Fluorine

Option D: Fluorine

Explanation:

From the periodic table, Nickel and Sodium are metals. Which means that they are good conductors of electricity.

While silicon is a metalloid. A metalloid has properties of both metals and nonmetals. Thus, it has tendencies to conduct electricity.

Fluorine is a non - metal which means that it doesn't conduct electricity.

Thus, the most likely that is not a good conductor is Fluorine.

its first and third is your answer i did the qustion the fourth isnt right
