A student compares the resonance contributors of the fulminate ion, which has the connectivity \(\text{C}-\text{N}-\text{O}\), with those of the cyanate ion, which has the connectivity \(\text{O}-\text{C}-\text{N}\). Each ion has \(16\) valence electrons. Lone pairs are not shown, but every atom in each contributor has an octet.

Ion	Resonance contributors
Fulminate, \(\text{CNO}^{-}\)	\(F_1:[\text{C}\equiv\text{N}-\text{O}]^{-}\quad F_2:[\text{C}=\text{N}=\text{O}]^{-}\quad F_3:[\text{C}-\text{N}\equiv\text{O}]^{-}\)
Cyanate, \(\text{OCN}^{-}\)	\(Y_1:[\text{O}-\text{C}\equiv\text{N}]^{-}\quad Y_2:[\text{O}=\text{C}=\text{N}]^{-}\quad Y_3:[\text{O}\equiv\text{C}-\text{N}]^{-}\)

Using formal-charge magnitude and electronegativity, which statement correctly identifies and justifies the dominant contributor to each resonance hybrid?
