Chemistry students use the phrase “LEO says GER” and “LEO the lion goes GER” to keep the two halves of a redox process straight, since the Loss of Electrons is Oxidation while the Gain of Electrons is Reduction.<ref>Buell, Phyllis; James Gerard (2002). Chemistry Fundamentals: An Environmental Perspective, Jones and Bartlett. ISBN 0-7637-1074-1. p. 208: “When a substance loses an electron, it is oxidized; when it gains an electron, it is reduced (LEO says GER)”</ref>

Another version is the word “OIL-RIG”, meaning Oxidation Is Loss, Reduction Is Gain (of electrons).<ref>Bland, Will J.; David Rolls (1998). Weathering: An Introduction to the Scientific Principles, Oxford University Press US. ISBN 0-340-67744-9 . p. 75: “It is helpful to remember ‘OIL RIG:’ Oxidation i loss of electrons (’OIL’), Reduction is gain of electrons (’RIG’).”</ref>
