Which of the following reasons explains why there is a decimal for most atomic masses?
The mass of one atom can have a fraction.
Since electrons are very small mass they only add a little bit, usually only a decimals worth.
It is the average mass of all the potential isotopes of an atom.
Neutrons have a mass of 1.1 meaning that fractions are common.
