Ответ:
Four electrons are bounded by eight electrons
and the bond order = 4/3
Explanation:
The molecular ion has 24 valence electrons and The SN of N in the central of the structure is = 3 according to VSEPR Theory. and this depicts trigonal planar geometry about the central nitrogen also this corresponds to sp^2 hybridization of the valence orbital of the atom N.
The 6 valence electrons are shared between N and O's, while the 2p orbital of Nitrogen will combine with the 2p orbital on each oxygen atoms in order to form four (4) π molecular orbitals. the binding orbital is occupied by a pair of electrons. Four electrons are bounded by eight electrons
and the bond order = 4/3
Attached below is the Lewis structure and resonance structures of the ion ( NO^- 3 )
