Oxidation in a redox reaction involves which of the following?
Electrons lost
A redox reaction is a coupled process in which one species is oxidised while another is simultaneously reduced through transfer of electrons.
By the electronic definition, oxidation is the loss of electrons by an atom, ion or molecule, which raises its oxidation number.
The mnemonic OIL RIG summarises this idea: Oxidation Is Loss of electrons, Reduction Is Gain of electrons.
Protons, being nuclear particles, are not exchanged in ordinary chemical redox reactions.
Hence, oxidation in a redox reaction involves the loss of electrons.
