These three pieces of data are the elemental symbol, the atomic number (typically given the symbol, Z, and the atomic weight. In its simplest form (shown below), each entry only has three pieces of information that you will need to know. There you can find the metals, semi-conductor(s), non-metal(s), inert noble gas(ses), Halogens, Lanthanoides, Actinoids (rare earth elements) and transition metals. The periodic table can often be presented with an abundance of data about each and every element listed. IUPAC Periodic Table of the Elements 18 1 H hydrogen 1.007 94(7) 2 Key: 13 14 15 16 17 4 atomic number 5 6 7 8 9 Be Symbol B C N O F beryllium name boron carbon nitrogen oxygen fluorine 9.012 182(3) standard atomic weight 10.811(7) 12. The atomic mass is the average mass of an element in atomic mass units (amu. Please note that the elements do not show their natural relation towards each other as in the Periodic system. Download this Web Site to your computer (Adobe Acrobat format - PDF). When the chemical elements are thus arranged, there is a recurring pattern called the periodic law in their properties, in which elements in the same column (group. The unity for atomic mass is gram per mol. periodic table, in chemistry, the organized array of all the chemical elements in order of increasing atomic number i.e., the total number of protons in the atomic nucleus. I hope you have got the complete list of 118 elements and their symbols and atomic number along with their atomic mass. The lightest chemical element is Hydrogen and the heaviest is Hassium. The elements whose atomic masses are written in bracket ( ) are the synthetic elements and their atomic masses values represent the Atomic Mass of the most stable isotope. The chemical elements ofįor chemistry students and teachers: The tabular chart on the right is arranged by Atomic mass (weight). This list contains the 118 elements of chemistry.
