Chemical elements listed by atomic mass The elements of the periodic table sorted by atomic mass. click on any element's name for further information on chemical properties, environmental data or health effects. This list contains the 118 elements of chemistry.

Atomic weights found within a periodic table one might think are constant. The truth is that atomic weights have changed as a function of time. Since 1899 the IUPAC Commission on Isotopic Abundances and Atomic Weights ( CIAAW) has been evaluating atomic weights and abundances.

This is a periodic table with atomic mass, element name, element symbol, and atomic number. The atomic mass is the average number of protons and neutrons in atoms of a chemical elements, allowing for the natural abundances of the element’s isotopes.This table uses the latest accepted single values because it makes chemical calculations easier.

Notes on the Atomic Mass of particular elements: Technetium: Atomic mass number given for longest lived isotope. Polonium: Atomic mass number given for longest lived isotope. Astatine: Atomic mass number given for longest lived isotope. Radon: Atomic mass number given for longest lived isotope.

So why DO we seem to concentrate on the "gram" as our go to guy on the periodic table for atomic weights and ultimately for molar masses and molecular weights?

The periodic table provides us with a comprehensive view of the various elements. Along with atomic mass and atomic number values, this table helps us to understand the various properties, abbreviations, and names of all the elements present in nature. The following article will help you to gain more information about the same.
