Consider the transition metal complex Ni(CN)₃(H₂O)₂^3-.The total number of valence electrons this complex possesses is ____. A)2 B)8 C)10 D)12 E)18

Question

Quizplus · Accepted Answer

To determine the total number of valence electrons in the complex, we need to count the valence electrons of each atom and the charge on the complex.

Ni: 1 atom x 10 valence electrons = 10 
C: 1 atom x 4 valence electrons = 4 
N: 1 atom x 5 valence electrons = 5 
S: 3 atoms x 6 valence electrons = 18 
H: 1 atom x 1 valence electron = 1 
O: 1 atom x 6 valence electrons = 6 
P: 1 atom x 5 valence electrons = 5 
Charge: -1

Total = 10 + 4 + 5 + 18 + 1 + 6 + 5 - 1 = 48 valence electrons

Therefore, the best choice is E (18 valence electrons).
