Webdefined as 1⁄16 the mass of 16O). In the chemical atomic mass scale, the amu was defined as 1⁄16 of the average atomic mass of oxygen (which included the contribu-tion of the low-abundance isotopes 17O and 18O). Both scales were internally ac-curate, but there was a difference factor of 1.000275 between them (physical scale chemical scale ...

The mass number is unique for each isotopeof an element and is written either after the element name or as a superscript to the left of an element's symbol. For example, carbon-12(12C) has 6 protons and 6 neutrons. Nominal mass[edit]
