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.

Activity series

K > Na > Mg > Al > Zn > Cr > Fe > Pd > H > Cu > Au
  • Kangaroos Naturally Muck About in Zoos For Purple Hippos Chasing Aardvarks.[1]
  • Katty's Naughty Cat Mingled with Alice and Zarina; Fearlessly Plundering Her Cupboard of Gold.[2]
Potassium > Sodium > Calcium > Magnesium > Aluminum > Zinc > Iron > Lead > Copper > Silver > Gold.

Atomic orbital

Sequence of orbitals

Further information: Spectroscopic notation
s p d f g h i k
  • Sober Physicists Don't Find Giraffes Hiding In Kitchens.

Note: After the k shell, they follow alphabetical order (skipping s and p as they came earlier).[4]

Aufbau principle

1s2 2s2 2p6 3s2 3p6 4s2 3d10 ...

The order of sequence of atomic orbitals (according to Madelung rule or Klechkowski rule) can be remembered by the following.

Order in which orbitals are arranged by increasing energy according to the Madelung rule. Each diagonal red arrow corresponds to a different value of n + l.

Cations and anions

Cations are positively (+) charged ions while anions are negatively (−) charged. This can be remembered with the help of the following mnemonics.

  • Cats have paws ⇔ Cations are pawsitive.[5]
  • Ca+ion: The letter t in cation looks like a + (plus) sign.[6]
  • An anion is a negative ion. (Anegativeion ⇒ Anion).[7]

Cation vs. anion: positive vs. negative

The t in cation looks like a plus sign: "ca+ion".

Cation is positive, anion is negative.[8]

Redox reactions

A redox reaction is a chemical reaction in which there is a change in oxidation state of atoms participating in the reaction.

Ions

An atom (or ion) whose oxidation number increases in a redox reaction is said to be oxidized (and is called a reducing agent). It is accomplished by loss of one or more electrons. The atom whose oxidation number decreases gains (receives) one or more electrons and is said to be reduced. This relation can be remembered by the following mnemonics.

  • Leo says Ger! or Leo the lion, Ger! can be used to represent Loss of electron is oxidation; Gain of electron is reduction.[9][10]
  • Oil Rig: Oxidation is loss; Reduction is gain (of electrons).[11]

Electrodes

An electrode in which oxidation takes place is called an anode while in that which reduction takes place is called cathode. This applies for both electrolytic and electrochemical cells, though the charge on them reverses. The red cat and an ox mnemonics are useful to remember the same.

  • Red cat: Reduction at cathode
An ox: Anode for oxidation.[12]
  • The words oxidation and anode, both begin with vowels.
Also, both reduction and cathode begin with consonants.[7]
  • Fat Cat: electrons flow From Anode To Cathode

−ate ions

Sulfate, Phosphate, Carbonate, Chlorate, Bromate, Iodate, Nitrate
  • Super Popeye Constantly Clubbed Brutus In Nevada.[13]
Nitrate, Bromate, Carbonate, Iodate, Chlorate, Chromate, Sulfate, Phosphate
  • Nick Brit the Camel ate an Inky Clam with Crêpes for Supper in Phoenix.

Number of consonants denotes number of oxygen atoms. Number of vowels denotes negative charge quantity. Inclusion of the word "ate" signifies that each ends with the letters a-t-e

Electronegativity

Fluorine > Oxygen > Nitrogen >Clorine > Bromine > Iodine > Sulphur > Carbon > Hydrogen ≥ Phosphorus
  • Pronounce: FONClBrISCHP.[14]

FONe CalL Brought to India,Sonias Congress Happy Position

(F)irst (O)ff, (Cl)ean (N)ow; (Br)ing (I)n (S)ome (C)aps, (H)alters, and (P)ants.

Electrochemical series

Potassium > Calcium > Sodium > Magnesium > Aluminium > Zinc > Iron > Tin > Lead > Hydrogen > Copper > Silver > Gold
  • Paddy Could Still Marry A Zulu In The Lovely Honolulu Causing Strange Gazes.[15]
