Mass of elements 1 to 20
WebPeriodic Table Atomic Mass in the Periodic Table of Elements Relative atomic mass is the ratio of the average mass of the atom to the unified atomic mass unit (symbol: u) or dalton (symbol: Da), which is defined as one twelfth of the mass of a carbon-12 atom in its ground state. Choose Elements to Display Plot of Atomic Mass vs Atomic Number Webas the atomic mass. Notes Note 1: The element does not have any stable nuclides, and a value in brackets, e.g. [209], indicates the mass number of the longest-lived isotope of the element. However, three elements, Thorium, Protactinium, and Uranium, have a characteristic terrestrial isotopic composition, and thus their atomic mass given.
