List of chemistry mnemonics

Many chemistry aspects, rules, names of compounds, sequences of elements, their reactivity, etc., can be easily and efficiently memorized with the help of mnemonics.

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

The atom whose oxidation number decreases gains (receives) one or more electrons and is said to be reduced.

Inclusion of the word "ate" signifies that each ends with the letters a-t-e. To use this for the -ite ions, simply subtract one oxygen but keep the charge the same.

[30] From R group moving around the ring:[30] The four most common elements in living organisms – carbon, hydrogen, oxygen, and nitrogen – may be remembered with the acronym CHON.

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 .
