Interpretation:
The oxidation number of each atom in give ion should be assigned
Concept introduction:
Oxidation Numbers:
Oxidation Numbers is number, which gives the information about the number of electrons lost or gained by atom or element in the formation of compound by
In generally an atom are ion gains an electron from redox reaction is known as reduction and the atom are ion loosed its electron in redox reaction is known as oxidation.
Oxidation increases the positive charge on atom or ion and reduction increases the negative charge on atom or ion.
The total oxidation number of molecules are zero, noble gases and elemental form of all atoms are having 0 oxidation number.
The common oxidation number for Hydrogen is +1, Oxygen is -2, halides -1, earth metals are +1 and alkaline earth metals are +2.
