(A) To determine if a molecule or ion has an odd number of electrons,we calculate the total valence electrons:$A. NO_2$: $5 + 2(6) = 17$ (Odd)$B. ICl_4^{-}$: $7 + 4(7) + 1 = 36$ (Even)$C. BrF_3$: $7 + 3(7) = 28$ (Even)$D. ClO_2$: $7 + 2(6) = 19$ (Odd)$E. NO_2^{+}$: $5 + 2(6) - 1 = 16$ (Even)$F. NO$: $5 + 6 = 11$ (Odd)The species with an even number of electrons are $ICl_4^{-}$,$BrF_3$,and $NO_2^{+}$.Therefore,the total count is $3$.

The number of molecules or ions from the following,which do not have an odd number of electrons are $...............$.
$A. NO_2$ $B. ICl_4^{-}$ $C. BrF_3$ $D. ClO_2$ $E. NO_2^{+}$ $F. NO$
