Label the na and cl as either + or -. and label each as either cation or anion

Na⁺ Cl⁻

Explanation:

Sodium form cation by losing one electron and chlorine form anion by accepting one electron. Both form ionic compound sodium chloride.

Ionic bond:

It is the bond which is formed by the transfer of electron from one atom to the atom of another element.  

Both bonded atoms have very large electronegativity difference. The atom with large electronegativity value accept the electron from other with smaller value of electronegativity.

For example:

Sodium chloride is ionic compound. The electronegativity of chlorine is 3.16 and for sodium is 0.93. There is large difference is present. That's why electron from sodium is transfer to the chlorine. Sodium becomes positive and chlorine becomes negative ion.
