the crystal structure of nabr is represented in the diagram above. which statement correctly compares crystalline nabr(s) to molten nabr(l) in terms of electrical conductivity?\n(a) crystalline nabr contains no freely moving electrons that could conduct an electrical current, whereas electrons can flow freely in molten nabr, which is a good conductor of electricity.\n(b) crystalline nabr and molten nabr both contain ions that are held in fixed positions due to strong electrostatic attractions among the ions, making neither a good electrical conductor.\n(c) crystalline nabr and molten nabr both contain na atoms that transfer electrons to br atoms in a chemical reaction, thus allowing them both to be good conductors of electricity.\n(d) crystalline nabr contains no freely moving electrons to conduct electricity, but molten nabr is composed of freely moving na+ and br- ions, which allows it to be a good conductor of electricity.

Answer

Explanation:

Step1: Analyze the nature of ionic compounds

Ionic compounds like (NaBr) have ions ((Na^{+}) and (Br^{-})). In the crystalline form, the ions are held in fixed positions by strong electrostatic attractions. So, there are no freely - moving charged particles (ions or electrons) to conduct electricity.

Step2: Analyze the molten state of ionic compounds

When (NaBr) is molten, the ions ((Na^{+}) and (Br^{-})) can move freely. The movement of these charged ions allows the conduction of electricity.

Answer:

B. Crystalline (NaBr) and molten (NaBr) both contain ions that are held in fixed positions due to strong electrostatic attractions among the ions, making neither a good electrical conductor.
