OIL RIG: Oxidation Is Loss, Reduction Is Gain (of electrons)
Real World
A lithium-ion battery in a Tesla Model 3 powers the car through redox reactions: lithium is oxidised at the anode (loses electrons) while cobalt oxide is reduced at the cathode, releasing electrical energy.
Exam Focus
Always identify which species is oxidised and which is reduced by showing oxidation state changes — don't just state 'redox occurred'.
