The oxidation number of each atom in the given compounds.
Answer to Problem 22R
Oxidation state of sodium is +1 and chlorine is -1 in sodium chloride compound. The oxidation state of oxygen in Iron (II) oxide is -2.
Explanation of Solution
Given:
The compounds are Sodium chloride and iron (II) oxide.
Calculation:
Oxidation state of each atom in the compounds can be determined as
Sodium Chloride:
Sodium belongs to group 1 and it has 1 electron in the outermost shell. Therefore, oxidation state of the sodium is +1.
Chlorine belongs to group 17 and it has 7 electrons in its outermost shell and it requires 1 more electron to get noble gas configuration and thus it has the oxidation state of -1.
Therefore, oxidation state of sodium is +1 and chlorine is -1 in sodium chloride compound.
Iron (II) oxide:
Iron is a
Conclusion:
Hence, oxidation state of sodium is +1 and chlorine is -1 in sodium chloride compound. The oxidation state of oxygen in Iron (II) oxide is -2.
