How many electrons are present in 3d - orbital of tetrahedral `K_(2) [NiCl_(4) ]` complex ?

Options

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

Answer

A

Explanation

For complex `,K_(2) [NiCl_(4)]`
oxidation number of Ni =+2
Electronic configuration of `""_(28)Ni^(2+):`
`1s^(2),2S^(2)2P^(6),3S^(2)3p^(6),3d^(8)`
