We can write three resonance structures for the thiocyanate ion, CNS⁻.
Only the first two structures are important. We can ignore the third structure, because it has charge separation. There are formal charges on both N and S.
The resonance hybrid has the structure
The negative charge is slightly greater on N than on S, because N is more electronegative than S.
Hope this helps.
