No the teacher is correct. Think about how sodium and chlorine ionically bond- sodium can 'give' one electron and chlorine can 'gain' one electron

The first equation is correct.

Na is a group 1 metal, therefore it has a charge of 1+ while a chloride atom has a charge of 1-, equalling the charges out.

I forgot about linking ions. Thanks!
