Amnemonicis 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.
An atom (or ion) whose oxidation number increases in a redox reaction is said to be oxidized (and is called areducing agent). It is accomplished by loss of one or moreelectrons. 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.
