XeF₃^- check no of bond pairs and subtract that from the no. of valence electrons

remember that for O no. of electrons in bond pairs = 2 (its because there is an extra pi bond in addition to the sigma bond)
and for F it is 1

one piece of advice....since the qs r of not lengthy type.....plz post the Qs of a particular topic in one thread only.....it creates a messy scene wen u see half of the recent topics of jus bonding only[3]

@Eragon
