Answer:
NaCl
Step-by-step explanation:
The only chemical species that shows an ionic compound is NaCl.
NaCl is an ionic compound that conducts electricity in molten state due to presence of free mobile electrons in the structure when molten.
- An ionic bond typically forms between a metal and non-metal.
- In the compound NaCl, Na is the metal and Cl is the non-metal.
- The difference in electronegativity allows for this bond type to form.
