Question

using Valence Bond Theory predict the no. of unpaid electrons, magnetic properties, magnetic moment, IUPAC nomenclature ang Geometry for [Ni(NH3)6]²+​

Answer 1

Explanation:

Ni has an electronic configuration of 4s2,3d8 therefore, Ni2+ has an electronic configuration of 4s0, 3d8. Electrons are always removed from the 4s atomic orbital first.

since these are two unpaired electrons and

so the species is paramagnetic in nature .

sp3d2 hybridization therefore shape is octahedral

Number of unpaired electrons=2

magnetic moment =2.83 B.M
