How many electrons are needed in pbr3
WebPBr3 total valence electrons = 5 (P) + 7×3 (Br3) = 26 Hence, there are total 26 valence electrons in PBr3 lewis structure. PBr3 lewis structure showing valence electrons Next is to choose the lowest electronegativity atom from the molecule or structure. WebNov 23, 2016 · pkmnmushy Here is the answer for the three of them N20 = 16 e- SeCl2 =20 PBr3 = 26 Remember that to find the valence electrons in an atom you need to identify what group the element is in. An element in group 1A has 1 valence electron. If the element is in group 2A, then it has two valence electrons. Advertisement
