What is the electron configuration of V3+? [Ar]4s23d3 [Ar]4s23d0 [Ar]4s03d2 [Ar]4s23d5 What are possible correct quantum numbers for two outer most valence electrons in V3+? 3,3,-2, +1/2 AND 3,3,-1, + 1/2 3,2,-2,+ 1/2 AND 3,2,-1, + 1/2 4,1,0 + 1/2 AND 4,1,0, - 1/2 4,0,0+ 1/2 AND 4,0,0, - 1/2 How many unpaired electrons does V3+ have? Three One None Two Is V3+ paramagnetic or diamagnetic? Why? Diamagnetic because it has paired electrons Paramagnetic because it has unpaired electrons Paramagnetic because it has paired electrons Diamagnetic because it has unpaired electrons
