Loss of electrons is oxidation

Gain of electrons is reduction

Explain why redox is a two way process

Electron control lost by one atom is gained by another. Reduction and oxidation occur at the same time

Between reduction and oxidation. What involves the gain of electrons?

Reduction

Between reduction and oxidation. What involves the loss of electrons?

oxidation

Oxidising agents

Substances that cause oxidation in the substance they react with. Substance being oxidised loses electrons to the oxidising agent. As the oxidant agent gains electrons it is being reduced

Oxidising agents can be defined as

Electron acceptors

Reducing agent

Cause reduction with the substance they react with. Substance being reduced gains electrons from the reducing agent. As the reducing agent loses electrons it is being oxidised

Reducing agent can be defined as

Electron donors

Definition of reduction

Oxidation number of an atom has become more negative, control over electrons has been gained. The substance containing the atom has been gained

definition of oxidation

Oxidation number of an atom has become more positive, control over electrons has been lost. The substance contained the atoms has been oxidised.

Are most metals oxidising or reducing agent?

Reducing agents

Is group 17 oxidising or reducing agents?

Strong oxidising agent
