To calculate: the oxidation number of iron (Fe) in the compound
Answer to Problem 52R
The oxidation number of iron (Fe) in
Explanation of Solution
Introduction:
The oxidation number of an element corresponds to the number of electrons gained or lost by the last elements. It is generally equal to the group number.
The electronic configuration of sulfur is
Iron loses 3 electrons, 2 from 4s, and 1 from 3d sub shell in order to get half-filled d subshell. The stability of half-filled is greater.
Sulfur gains 2 electrons in order to complete its octet.
Therefore, the oxidation state of iron is +3 in
Conclusion:
Hence, the oxidation number of iron (Fe) in
