Question

How many electrons are present in 3d orbital of tetrahedral $K_2[NiC{l}_4]$ complex?

• A. 8 electrons
• B. 10 electrons
• C. 7 electrons
• D. 6 electrons

Answer 1

Answer: (A)

For complex $K_2[NiC{l}_4]$
Oxidation number of Ni= +2
Electronic configuration of 28 Ni 2+ :
$1s^2,2s^{2}2p^6,3s^{2}3p^{6}3d^8$
