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. (Atomic mass is also referred to as atomic weight, but the term "mass" is more accurate.)
Density – Atomic Mass and Atomic Number Density Atomic Weight. The atomic mass is carried by the atomic nucleus, which occupies only about 10 -12 of the total volume of Atomic Number Density. The atomic number density (N; atoms/cm 3 ), which is associated with atomic radii, is the number

It provides atomic mass, mass excess, nuclear binding energy, nucleon separation energies, Q-values, and nucleon residual interaction parameters for atomic nuclei of the isotope N-15 (Nitrogen
Mass number is always a whole number while atomic mass is not (except in the case of carbon-12 when expressed in u. The ratio of atomic mass to mass number is always closed to one. This is shown in the table below. a unit of mass, equal to 1/12 the mass of the carbon-12 atom and used to express the mass of atomic and subatomic particles. The dalton or unified atomic mass unit is a unit of mass widely used in physics and chemistry. It is defined as 1/12 of the mass of an unbound neutral atom of carbon-12 in its nuclear and electronic ground state and at rest.
The Atomic mass unit [u] to gram [g] conversion table and conversion steps are also listed. Also, explore tools to convert Atomic mass unit or gram to other weight and mass units or learn more about weight and mass conversions. Measurements of the atomic mass of a neutron and a proton yield these results: proton = 1.00728 amu neutron = 1.00867 amu Helium contains two protons and two neutrons, which should theoretically give helium nucleus a mass of 4.03190 amu.
