To figure out the position of equilibrium we could look at our pKa values and say, "Alright on the left we have negative two, on the right we have negative three." And we know that the equilibrium, the equilibrium favors the acid with the higher pKa value, favors the formation of the acid with the higher pKa value.

Hydrogens only need 2 valence electrons to have a full outer shell, so they're OK. So we have 8, 10, 12, and then we'll go back to the central atom, 14. So we've used all 14 valence electrons. At this point in the NH2OH Lewis structure, all of the Hydrogens have 2 valence electrons.

Neither resonance structure completely describes the electrons in the π bonds. They are not located in one position or the other, but in reality are delocalized throughout the ring. Valence bond theory does not easily address delocalization. Bonding in molecules with resonance forms is better described by molecular orbital theory. VSEPR Theory (Molecular Shapes) A = the central atom, X = an atom bonded to A, E = a lone pair on A Note: There are lone pairs on X or other atoms, but we don't care.

On the terminology. Alchimista already explained most of this, however, I cannot stress enough: There is no such thing as a most stable resonance structure. Therefore when you say common, you probably mean large contribution to the wave function, and when you say rare, you probably mean little contribution.
