A mnemonic is a memory aid used to improve long-term memory and make the process of consolidation easier. Many chemistry aspects, rules, names of compounds, sequences of elements, their reactivity, etc., can be easily and efficiently memorized with the help of mnemonics. This article contains the list of certain mnemonics in chemistry.
The thermodynamic square (also known as the thermodynamic wheel, Guggenheim scheme or Born square) is a mnemonic diagram attributed to Max Born and used to help determine thermodynamic relations. Born presented the thermodynamic square in a 1929 lecture. [ 1 ]

The numbers 200-900 would be confused easily with 22 to 29 if they were used in chemistry. khīlioi = 1000, diskhīlioi = 2000, triskhīlioi = 3000, etc. 13 to 19 are formed by starting with the Greek word for the number of ones, followed by και (the Greek word for 'and'), followed by δέκα (the Greek word for 'ten').
Knuckle mnemonic. A mnemonic for the number of days in each month uses the knuckles (and the dips between them) of two fists, held together, moving right from the left pinky knuckle. The raised knuckles can be seen as the 31-day months, the dips between them as the 30-day-months (and February). The gap between the hands ignored.
CHNOPS and CHON are mnemonic acronyms for the most common elements in living organisms. "CHON" stands for c arbon , h ydrogen , o xygen , and n itrogen , which together make up more than 95 percent of the mass of biological systems. [ 1 ] "

A circle mnemonic [3] was advanced which provides the MO energies of the system; this was the counterpart of the Frost–Musulin mnemonic [6] for ordinary Hückel systems. It was concluded that 4 n electrons is the preferred number for Möbius moieties in contrast to the common 4 n + 2 electrons for Hückel systems.
