The orbital diagram for the highest energy subshell of iron \( \left.{ }_{26} \mathrm{Fe}\right) \) is: \[ \begin{array}{l} 3 d^{6} \stackrel{\uparrow \downarrow}{\uparrow \downarrow} \uparrow \downarrow \uparrow- \\ 3 d^{5} \stackrel{\uparrow}{\uparrow} \uparrow \stackrel{\uparrow}{-1} \\ 3 d^{6} \stackrel{\uparrow \downarrow}{\uparrow} \uparrow \end{array} \]
