{{Sugdef|mass number|
the term "mass number" is substituted by the term [[Nucleon number|nucleon number]] for the following reasons:


# the physical property named mass number is dimensionless and hence not a mass
# the symbol m which was often used for the physical quantity mass number is reserved for mass
# this definition of mass number is not consistent because it is always a whole number, whereas m/z is used for real numbers
}}

The definition on the front page should be
{{Sugdef|nucleon number|
The number of the protons and neutrons in an atom, molecule or ion.
("sum of protons" is not well defined, it sould be "the sum of number of protons and number of neitrons")
}}
