Concept explainers
(a)
Interpretation:
The oxidation state of the metal in complex
Concept introduction:
Oxidation state or oxidation number indicates the extent of oxidation of the atom in the compound. It is usually represented as a positive or negative charge on the atom.
In other words, it indicates the loss of electrons of the atom in a chemical compound. The number indicates the number of electrons that an atom can gain or lose.
(b)
Interpretation:
The oxidation state of the metal in complex
Concept introduction:
The extent of oxidation of the atom in the compound is the oxidation number or oxidation state. It is indicated as a positive or negative number.
In other words, it indicates the loss of electrons of the atom in a chemical compound. This indicates the number of electrons that an atom can gain or lose.
(c)
Interpretation:
The oxidation state of the metal in complex
Concept introduction:
The extent of oxidation of the atom in the compound is the oxidation number or oxidation state. It is indicated as a positive or negative number.
