(i)${\text{IBr}}_2^{-}$



number of the electron in the valence shell$=7+7+7+1=22$

(ii)${\text{BeCl}}_{\text{2}}$



${\text{sp}}^{\text{3}}\text{d}$hybridised (linear).

Number of the electron in the valence shell$=2+7+7=16$

(iii)${\text{XeF}}_{\text{2}}$



number of electron in valence shell$=$$8+7+7=22$

(iv)${\text{TeI}}_{\text{2}}$



number of the electron in the valence shell$\text{= 6+7+7=24}$

(v)${\text{IF}}_{\text{3}}$



number of the electron in the valence shell$=7+7+7+7=28$

${\text{IBr}}_2^{-}$and${\text{XeF}}_{\text{2}}$both are isostructural and isoelectronic.
