Mass number is also called atomic mass number. The A probably comes from atomic. The symbol M means molar mass. --Tsemii 11:04, 15 Oct 2004 (UTC)

I have changed the symbol listed here for neutrons and protons to lowercase p's and n's. It is important to keep these symbols in the lowercase when editing this article in the future. Ring-Ding 02:21, 29 September 2006 (UTC)
