Answer
Loss of electrons
Explanation
Oxidation is defined as the loss of electrons in a chemical reaction.
Common mistake
Misunderstanding Electron Transfer
Students often confuse the concept of electron transfer in displacement reactions, thinking that the metal being displaced is gaining electrons instead of losing them.
To fix this, students should remember that in a displacement reaction, the more reactive metal loses electrons (is oxidised) while the less reactive metal gains those electrons (is reduced).
