What is the Molecular Orbital diagram for N2-

I have the MO diagram for N2 and N2+ but don't know how to use that infromation to find the diagram for N2-.

Also, does anyone know the orbital diagram (condenced) for Mn? or if Mn is paramagnetic or diamagnetic and how to know that?

The MO is the same as that of N2 but containing one more electron in the next available orbital.
Mn is paramagnetic because it has an odd number of electrons (7 total).
