no because there is only one way to arrange the electrons around it
No. First of all, the bond is technically ionic, although at high temperatures, it may behave as a single covalent bond. Still, even if the bond is covalent in character, there will not be any resonance because you need a compound that contains both single and double covalent bonds to exhibit resonance.
