The atomic mass of an element is the average mass of the atoms of an element measured in atomic mass unit (amu, also known as daltons, D). The atomic mass is a weighted average of all of the isotopes of that element, in which the mass of each isotope is multiplied by the abundance of that particular isotope.

Games/Toys Not to be confused with the mass number, the atomic mass is the mass of an entire atom, including its protons, neutrons and electrons.

Note that, each element may contain more isotopes, therefore this resulting atomic mass is calculated from naturally-occuring isotopes and their abundance. The unit of measure for mass is the atomic mass unit (amu).

Although the SI unit of mass is kilogram, the atomic mass is often expressed in the non-SI unit dalton where 1 dalton is defined as 1⁄12 of the mass of a single carbon-12 atom, at rest. The protons and neutrons of the nucleus account for nearly all of the total mass of atoms, with the electrons and nuclear binding energy making minor contributions. Thus, the numeric value of the atomic mass when expressed in daltons has nearly the same Atomic Mass and Uncertainty [u] Half Life and Uncertainty Discovery Year Decay Modes, Intensities and Uncertainties [%] 14 F. 14.034315199 ± 0.000044142: 500 ys ± 60: A is correct for Fluorine, F, has an atomic number of 9 and an approximate atomic mass of 19.
