Explore how atomic mass changes with atomic number in the periodic table of elements via interactive plots.

See table 1 for details of range and original paper for the atomic weight of the element from different sources.

The latest release of the Periodic Table (dated 4 May 2022) includes the most recent abridged standard atomic weight values released by the IUPAC Commission on Isotopic Abundances and Atomic Weights (CIAAW), compiled as part of the 2021 Table of Standard Atomic Weights 2021.

Given below is a table that lists the first 30 elements based on atomic number and their corresponding atomic mass. The Molecular mass of an element can be calculated by adding the atomic masses of each of its constituents.

This is a list of chemical elements, sorted by relative atomic mass, or more precisely the standard atomic weights, (most stable isotope for artificial elements) and color coded according to type of element.

2020年4月6日 · 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.
