Vedclass · Answer

(C) The number of electrons in each species is as follows:$Ne$ (Atomic number $10$): $10$ electrons.$O^{2-}$ (Atomic number $8$): $8 + 2 = 10$ electrons.$Na^{+}$ (Atomic number $11$): $11 - 1 = 10$ electrons.$Na$ (Atomic number $11$): $11$ electrons.Since $Ne$,$O^{2-}$,and $Na^{+}$ are isoelectronic (all have $10$ electrons),$Na$ is the species that does not have the same number of electrons.
