The anion barO(8 + 1 = 9 electrons) is isoelectronic with N2- (7 + 2 = 9 electrons). Isoelectronic species have same number of electrons. (N3- = 7 + 3 = 10e-, F- = 9 + 1 = 10e- and Ne = 10e-).

Q. The anion $O^{-}$ is isoelectronic with

$N^{2 -}$

$F^{-}$

$N^{3 -}$

$N e$

The anion $\overset{ˉ}{O} (8 + 1 = 9$ electrons) is isoelectronic with $N^{2 -} (7 + 2 = 9$ electrons). Isoelectronic species have same number of electrons. $(N^{3 -} = 7 + 3 = 10 e^{-}$ , $F^{-} = 9 + 1 = 10 e^{-}$ and $N e = 10 e^{-})$ .

Q. The anion O− is isoelectronic with

N2−

F−

N3−

Ne
