+3 oxidation state is most common in

Question

+3 oxidation state is most common in (A) Ni (28) (B) Fe (26) (C) Zn (30) (D) Cu (29)

Tardigrade Admin · Accepted Answer

+3 oxidation state is most common in Fe as electronic configuration of Fe is 3d6 4s2. Therefore electronic configuration o f Fe(III) is 3d5 4s0 due to the extra stability associated with half-filled orbitals

Q. $+ 3$ oxidation state is most common in

$N i (28)$

$F e (26)$

$Z n (30)$

$C u (29)$

$+ 3$ oxidation state is most common in $F e$ as electronic configuration of $F e$ is $3 d^{6} 4 s^{2}$ .
Therefore electronic configuration o f Fe(III) is $3 d^{5} 4 s^{0}$ due to the extra stability associated with half-filled orbitals

Q. +3 oxidation state is most common in

Ni(28)

Fe(26)

Zn(30)

Cu(29)
