1.	Explain the terms ‘oxidation’ and reduction’ with reference to an atom or ion.
Answer» Oxidation: Loss of one or more electrons by an atom or ion is called oxidation. For example, Na → Na⁺ + e^– Fe²⁺ → Fe³⁺ + e^- Mg → Mg²⁺ + e^- Reduction: Gain of one or more electrons by an atom or ion is called reduction. For example, F + e^– → F^– O + 2e^- → O^2– Cu²⁺ + e^– → Cu⁺ Zn² + 2^e– → Zn

Explain the terms ‘oxidation’ and reduction’ with reference to an atom or ion.

Answer»

Oxidation: Loss of one or more electrons by an atom or ion is called oxidation.

For example,

Na → Na⁺ + e^–

Fe²⁺ → Fe³⁺ + e^-

Mg → Mg²⁺ + e^-

Reduction: Gain of one or more electrons by an atom or ion is called reduction.

For example,

F + e^– → F^–

O + 2e^- → O^2–

Cu²⁺ + e^– → Cu⁺

Zn² + 2^e– → Zn
