Periodic Table with Atomic Mass (Atomic Weight) - Definition of Atomic Mass (Atomic Weight)

The definition of Atomic Mass (Atomic Weight): Atomic mass, or atomic weight, is the average mass of atoms (protons and neutrons) of an element, calculated using the relative abundance of Isotopes in a naturally occurring element.

For convenience due the limitations of screen width the interactive Periodic Table chart does not include the Lanthanides (group six) or Actinides (group seven) which reside between group 2 and group 3 of the
periodic table shown above. They are, however, listed separately in the interactive table below.

  • Periodic Table with Atomic Mass - The mass of an atom expressed in atomic mass units (amu)
  • Periodic Table with Atomic Mass - The atomic mass unit (amu) is a unit of mass used to express atomic and molecular weights, equal to one-twelfth of the mass of an atom of carbon-12. It is equal to approximately 1.66 x 10-27 kg
  • Periodic Table with Atomic Mass - Atomic masses do not always increase directly with relation to atomic number (number of protons)
  • Periodic Table with Atomic Mass - The atomic mass is not a whole number because it is the weighted average of the masses of the different isotopes of that element

Periodic Table with Atomic Mass (Atomic Weight) - Names of Element Symbols
Some of the Periodic Table names of the symbols of elements are derived from their names in the Greek, Latin or German languages. The elements with Greek of Latin names are the oldest elements known and the element symbols were allocated when these classic languages were those used by ancient scholars. There are only ten elements whose element symbol names are not immediately apparent. Learn these origins of names and symbols and the Periodic Table with Atomic Mass becomes easier to understand!
